A look inside the Icon of the Seas, the world's biggest cruise ship, as it prepares for voyage

By Kris Van Cleave , Analisa Novak

January 18, 2024 / 12:14 PM EST / CBS News

Royal Caribbean is redefining the cruise industry with its latest ship, the Icon of the Seas. This $2 billion floating resort is largely booked until 2026.

Spanning nearly 1,200 feet, the cruise ship has 20 decks, which makes the Icon of the Seas the world's largest cruise ship.

It's a city at sea, accommodating up to 7,600 passengers in 2,805 staterooms and nearly 10,000 people, including the crew. The ship offers different experiences that include seven pools — one is the largest on any ship — the world's first onboard water park with six water slides, theaters, a casino and over 40 dining and drinking spots.

Miami Icon of the Seas

Jay Schneider, Royal Caribbean's Chief Product Innovation Officer, says the cruise ship is more than just its amenities.

"It's really about iconic experiences," he said.

And despite its massive size, Schneider said the ship is designed to avoid feeling overcrowded.

"We have purposely designed the ship to give more space for people," he said. "We believe, even at 7,500 guests, it won't feel to you like your entire hometown has joined the ship," said Schneider.    

Luxury comes at a price on the Icon. A weeklong Caribbean cruise costs about $3,500 for two people in an average stateroom. For those seeking more luxury, the Ultimate Family Townhouse – a three-story suite complete with touchscreen tables and a slide – can go for up to $100,000 per trip. The Royal Loft, aimed at high-rolling adults, offers two bedrooms, a private hot tub, and a spacious balcony starting at $40,000.

Icon of the Seas Media Day

Colleen McDaniel, editor-in-chief at Cruise Critic, said that bigger ships benefit both passengers and cruise lines.

"It means more people can experience something. It means that there's a lot more amenities and activities onboard the cruise ship," McDaniel said. "The more people they can put on a cruise ship, of course, the better business they do, the more money they make."

Kevin Curran says the Icon took his breath away. Having followed the ship's construction for over a year, the Oregon resident said he's thrilled to be on its inaugural cruise from Miami.

"The more I watched the videos, the more I understood this was something special," he said.

Icon of the Seas Media Day

Cruising is surging in popularity. Last year, passenger volume outpaced pre-pandemic numbers, and this year is expected to hit a new high of 36 million as spending on experiences has climbed 65% since 2019.

From the bridge, Captain Hendrik Loy is overseeing what amounts to a three-day test drive to the Bahamas.

"There is still fine-tuning that needs to take place," said Loy.

The Icon also champions environmental responsibility. It's powered by liquefied natural gas, treats its own waste, and produces its own water.

The World’s Largest Cruise Ship Is Nearly 1,200 Feet Long

Scheduled to debut in January, the vessel can accommodate 5,600 guests and 2,350 crew members

The world’s largest cruise ship is almost ready to set sail.

Royal Caribbean’s massive new ship, Icon of the Seas , passed its inaugural round of sea trials with flying colors, bringing it one step closer to hitting the open ocean with passengers, the cruise line  announced late last month. If all goes as planned, the record-breaking vessel will begin sailing in the Caribbean in January 2024.

Just how big is Icon of the Seas ? Really big. As Jalopnik ’s Ryan Erik King writes, it’s the size of five Titantics. More specifically, Icon of the Seas measures 1,198 feet long—nearly a quarter of a mile—and has a gross tonnage of 250,800. All that space means it can accommodate 5,600 guests and 2,350 crew members.

The cruise line is positioning the vessel as “the ultimate family vacation,” as CEO Michael Bayley told reporters earlier this year, per  CNN ’s Maureen O’Hare.

“When you step back and look at all the energy and time that has gone into creating this ship, it is mind-blowing,” he added.

The previous world’s largest cruise ship was also a Royal Caribbean vessel, Wonder of the Seas , which spanned 1,188 feet long and featured 18 decks.

Crews in Turku, Finland, began work on Icon of the Seas in 2021. Last month, the vessel sailed the open ocean for the first time, as staffers spent four days testing the main engines, hull, brakes, steering system and other components. They also measured noise and vibration levels.

The vessel will undergo another round of sea trials later this year before officially launching in Miami early next year, according to Royal Caribbean. Icon of the Seas will primarily take cruisers to the islands of the eastern and western Caribbean on seven-night itineraries.

With progress on Icon of the Seas moving along, Royal Caribbean has already started building another large “icon class” ship. The cruise line expects that unnamed vessel to launch in 2025, per a  statement .

Icon of the Seas has 20 total decks, 7 swimming pools and 8 “neighborhoods,” or distinct areas with entertainment and dining. Another noteworthy feature is Category 6, which will be the largest waterpark at sea when Icon of the Seas sets sail.

The ship will be equipped with a special grooming robot that will clean the hull whenever it’s in port to help reduce drag and improve fuel efficiency by 3 to 4 percent, reports  TTG Media ’s Charlotte Cullinan.

Cruise ship in water

Icon of the Seas will also be the first ship in the cruise line’s fleet to run on liquefied natural gas and  fuel cells , which are similar to batteries but do not need to be recharged. Water is the main byproduct of fuel cells—which combine oxygen and hydrogen to produce energy—which should help the ship reduce its greenhouse gas emissions.

Liquefied natural gas , meanwhile, is a controversial energy source that involves cooling natural gas to a liquid state to make it easier to transport. The liquid version is “actually worse than ordinary gas,” writes the  Natural Resources Defense Council . “The energy required to chill, ship and regasify the fossil fuel makes it far more carbon-intensive and increases the potential for leakage of dangerous methane,” according to the organization.

Royal Caribbean’s leaders say they view liquified natural gas as a “ transitional fue l,” and that they hope to continue to  reduce the environmental impact of their ships moving forward. 

"[Liquefied natural gas] is about 20-30 percent better for the environment [than heavy fuel oil], but it’s still not going to be the solution,” Bayley tells TTG Media . “We don’t know the answer, but the whole industry is working towards the answer.”

What is the largest cruise ship in the world?

Ashley Kosciolek

Does size really matter? The cruise industry thinks so. For more than a century, cruise lines have competed to claim the title of world's largest cruise ship.

When it set sail in 1912, the ill-fated Titanic was the largest and grandest passenger vessel of its time. But, as of 2009, when Royal Caribbean debuted its first Oasis-class ship , the superlative applies to vessels more than five times Titanic's size.

So, what is the largest cruise ship in the world? At the time of publication, it's Royal Caribbean's Icon of the Seas . At 250,800 gross registered tons and carrying up to 7,600 passengers (plus 2,350 crew members), it's a true behemoth. It boasts eight neighborhoods that feature everything from water slides, an indoor AquaTheater, a carousel and an adults-only sun deck to lavish suites, retail shops, thousands of live plants and more than two dozen bars and restaurants.

But where do other cruise ships fall? Here's a quick rundown of the world's biggest cruise ships by gross registered tons and maximum passenger capacity. Unsurprisingly, Royal Caribbean's Icon Class and Oasis Class dominate the top five in both categories. Perhaps more surprisingly, only two other lines join it on the winner's podium.

Note: This article excludes ships from lines like Costa Cruises, P&O Cruises and Aida, which do not cater to the North American market.

Largest Cruise Ships - CruiseMapper

CruiseMapper's list of biggest cruise ships includes all vessels with gross tonnage/volume over 150,000 GT-tons .

Each one of these behemoth ships is an engineering marvel produced by our contemporary age of fun and super technologies. Kudos to their builders and double kudos to their proud owners who have invested so much in these newbuild projects!

Note: In the following table, all links are internal (CruiseMapper) and redirect to the liner's itinerary schedule where you can compare dates and prices per person (double occupancy cabin rates).

The world's largest river cruise ship is Victoria Sabrina . The 2020-launched riverboat is China-built, owned by Victoria Cruises China and deployed year-round on Yangtze River. The vessel has the impressive volume of 17000 GT-tons, LOA length 150 m (492 ft), width 22 m (72 ft), 7 decks (5 with cabins), 270 staterooms, max capacity 690 passengers plus 195 crew/staff.

Oasis-class - biggest cruise ship in the world ever built

World's currently largest cruise ship class is produced exclusively for RCI-Royal Caribbean andin 2 sub-series - Oasis-Class (Allure OTS, Oasis OTS) and Oasis-Plus (Harmony OTS, Symphony OTS, Wonder OTS). These are sisterships from the fleet of the second- largest cruise shipping company in the world - RCCL-Royal Caribbean Cruises Ltd (as shipowner) that follows only Carnival Corporation (as shipowner).

As to vessels' dimensions, each boasts the unimaginable weight of 227,000-230,000 GT / gross tons, LOA length 362 m (1187 ft) and waterline width 47 m (154 ft). The extreme breadth is over 60 m (198 ft). As the GT is a volume measurement, the ship's actual mass (called displacement) is approx 100,000 tons (the hull alone weighs about 54,000 tons). Surpassing all passenger ship standards, building cost and all previous ship travel vacation concepts, the Oasis-class ships are currently the only passenger shipping vessels of such immense size.

Other interesting numbers are the above waterline height (72 m / 236 ft), depth (23 m / 74 ft below waterline), 16 passenger decks, draft/draught (9,3 m / 31 ft), cruising/service speed 23 knots (26 mph / 42 kph), capacity 5400 passengers at double occupancy (max 6296 / 6870) and officers+crew capacity 2165.

The world's biggest cruise ship propulsion system guarantees the perfect maneuverability by 3 rotatable Azipod thrusters (suspended under the ship's stern), each with a huge electric motor and a 6 m (20 ft) propeller. The ship offers great stability due to its enormous size. And in times of need - there are 18 lifeboats, each with a capacity of 370 people.

Oasis-Plus class is also currently the world's most technologically advanced and energy-efficient cruise vessel ever built. It is equipped with a new-generation exhaust gas cleaning system (multi-stream scrubbers) and with a hull lubrication system allowing the ship to float on air bubbles (created around the hull) thus reducing drag and increasing fuel efficiency.

Regarding cruise accommodations , this class of vessels has some of the largest suites at sea - measuring 150 m2 (over 1600 ft2, balcony included). Another signature feature is the 7 "neighborhoods" (theme-park-like areas), 5 large swimming pools, a huge casino, a full-size volleyball/basketball court, large-capacity bars, and lounges. Oasis-Plus ships additionally have waterslides (created by Aquatic Design & Engineering) and a total of 23 "water fun" areas (swimming pools, large-size outdoor jacuzzies, waterslides, flowriders/surf simulators). The stern-located Ultimate Abyss water slide is 150 ft (45,70 m) above sea level. It features 31 sections, two 360-degree circles, 27-degree slide incline, 28 m (92 ft) serpentine-like drop, 13,14 seconds average sliding time (top to bottom), around 300 small LED lights and graffiti artworks throughout.

These phenomenal ships were manufactured by STX Europe (shipyard Turku Finland / Oasis-class) and in by STX France (shipyard Saint-Nazaire France / Oasis-Plus). The new Oasis ships are 2,15 m (7 ft) longer.

Biggest Carnival cruise ship - "Carnival Pinnacle" class

Watch this amazing YouTube video about the "Carnival Pinnacle cruise ship". The project was designed by the Italian shipbuilder Fincantieri as their biggest ever passenger ship - GT tonnage 200,000 tons, capacity 6000 passengers, length 380 m (1246 ft), The "Pinnacle Project" was initiated by Carnival Corporation in 2004 to tip the scales in the "Carnival vs Royal Caribbean" competition.

Carnival Pinnacle was never built as the project was officially canceled (mainly due to the vessel's incredible cost at that time). However, many of the project's elements and innovative design features were later adapted for other large-sized cruise liners built for rival companies.

Full List: The 10 Current Largest Cruise Ships on the Planet

If you think cruise ships have gotten bigger, it’s not just your imagination. Whereas a ship built in the 1990s might hold 2,500 passengers and come in at around 75,000 gross tons (a measure of ship size), that’s nowhere near the ships built today.

largest cruise ship that

Today, any new ship from a major line will be at least 140,000 gross tons, with many much larger than that. Passenger counts have also swelled, with many new ships carrying 5,000 cruisers when completely full.

But the largest cruise ships on the planet are in another league altogether. They can measure up to 250,000 gross tons (roughly triple the size of a ship built 30 years ago!) and when at full capacity with crew, have nearly 10,000 people onboard.

Why Are Cruise Ships So Big?

Truth be told, while the size of massive modern ships is staggering, not everyone likes the large ship experience. Some people can find them too crowded and too hard to navigate. But not everyone feels that way, and cruise lines have invested literally billions into building ships that are as large as possible. So what is the appeal of a mega ship?

Amenities/Activities: For passengers, the big advantage of size comes with everything that can be fit onto the ship. Instead of the old days where there was a pool, some loungers, and a buffet, modern mega ships are literal resorts at sea.

There are multiple pools, more than a dozen restaurants, casinos, ziplines, literal parks, ice-skating rinks, rock-climbing walls, spas, and more bars than you can count on your fingers and toes.

All of that combines into an experience that can exceed expectations and keep passengers coming back for more.

Efficiencies of Scale: For cruise lines, one big positive about a larger ship are greater efficiencies. Instead of having the cost of building two smaller ships — and the costs of having two sets of crew to run them both — one larger ship offers the chance for just as many passengers at a lower cost.

Marketing: Finally, one overlooked aspect of why cruise ships are bigger than ever has to do with marketing and publicity. There’s a certain awe and interest that comes with the world’s largest ships. Seeing them in port is essentially a giant billboard for a cruise line. And the largest ships also get significant press due to their size. All of that can translate into more interest, ticket sales, and prices for the newest — and biggest — ships.

With that in mind, here is the current list of the world’s largest cruise ships as of now…

Icon of the Seas

Icon of the Seas trials

When it comes to the largest ships, Royal Caribbean is the undisputed leader with the six biggest cruise ships in the world. But the king of the fleet — and the largest cruise ship in the world — is Icon of the Seas .

Icon of the Seas doesn’t sail with passengers until 2024, but it’s already made waves. It’s not just the massive size (250,800 gross tons and 7,600 passengers at maximum capacity), but what’s onboard. A full-fledged waterpark, seven different pools, and eight different neighborhoods offer a spot for everyone. This ship looks to change cruising forever.

  • Gross Tonnage: 250,800
  • Length: 1,198 feet
  • Passenger Capacity: 5,610 double occupancy; 7,600 max capacity
  • Year Built: 2023

Wonder of the Seas

largest cruise ship that

Wonder of the Seas is the latest edition of Royal Caribbean’s Oasis-class ships (until Utopia of the Seas arrives in 2024), which were the largest class in the world until the new Icon class took the torch. Still, it’s not as if Wonder of the Seas is a slouch.

At 235,600 gross tons, there’s room for 7,084 passengers and an amazing amount to see and do onboard. This includes Central Park, the mid-ship outdoor promenade that winds through lush gardens, and the AquaTheater, where performers put on aquatic shows, including towering high dives at sea.

  • Gross Tonnage: 235,600
  • Length: 1,188 feet
  • Passenger Capacity: 5,734 double occupancy; 7,084 max capacity
  • Year Built: 2022

Symphony of the Seas

largest cruise ship that

Each iteration of Oasis-class ships has arrived just slightly larger than the previous when it comes to gross tonnage. That means they each had their time as the largest in the world before another arrived on the scene. In this case, Symphony of the Seas (228,000 gross tons and the ability to hold 6,680 passengers) took the crown in 2018.

Today, it’s the third-largest cruise ship on the planet, but it’s no slouch. It holds seven different neighborhoods, nearly 3,000 staterooms, three waterslides, and Ultimate Abyss — a 10-story dry slide.

  • Gross Tonnage: 228,081
  • Passenger Capacity: 5,518 double occupancy; 6,680 max capacity
  • Year Built: 2018

Harmony of the Seas

largest cruise ship that

Built in 2016, Harmony of the Seas features 18 decks, more than 225,000 gross tons (about 10% smaller than Icon of the Seas) and can carry nearly 6,700 passengers when completely full. That’s good enough to make it the fourth-largest cruise ship in the world.

It features many of the same components of other ships in the class, like the adults-only Solarium, Central Park, and the AquaTheater. That’s not to mention 17 different spots to grab a bite to eat.

  • Gross Tonnage: 226,963
  • Passenger Capacity: 5,479 double occupancy; 6,687 max capacity
  • Year Built: 2016

Oasis of the Seas

largest cruise ship that

The ship that started the trend of truly mega ships is also the namesake of the Oasis class — Oasis of the Seas. If you notice, most of the largest ships on our list were built recently. This ship first began sailing in 2009 and set off the “arms race” of larger ships that continues today.

Following a refurbishment, it now features three waterslides, a dozen lounges, 2,801 cabins (including one with a panoramic view right above the ship’s bridge), a splash pad for kids, and even an escape room themed like the 1960s NASA mission control. And did we mention 20 different places to find something to eat?

  • Gross Tonnage: 226,838
  • Length: 1,187 feet
  • Passenger Capacity: 5,602 double occupancy; 6,771 max capacity
  • Year Built: 2009

Allure of the Seas

largest cruise ship that

Following a refurbishment of Oasis of the Seas, Allure of the Seas — which was the second ship in the class and built in 2010 — is actually now the smallest of the group based on tonnage. Still, that’s good enough for sixth largest in the world at “just” 225,000 gross tons.

On the ship, you’ll find 18 decks, 2,748 staterooms and more than 6,800 passengers when completely full. That’s definitely a lot of people, but remember that you also have a lot more space to spread out, giving plenty of elbow room.

  • Gross Tonnage: 225,282
  • Passenger Capacity: 5,496 double occupancy; 6,826 max capacity
  • Year Built: 2010

MSC World Europa

largest cruise ship that

While Royal Caribbean has a lock on the largest ships, the title of largest cruise ship from outside that cruise line goes to MSC World Europa.

Coming in at almost 216,000 gross tons, it’s roughly 14% smaller than Icon of the Seas. But don’t think it’s some slouch. From bumper cars to seven pools to an 11-story slide, there’s no shortage of things for kids to do. Adults will love the 13 different dining options and an indoor promenade or Panorama Lounge for shopping, having a drink, or just relaxing.

This ship will be joined in 2025 by sister-ship MSC World America, set to sail stateside.

  • Gross Tonnage: 215,863
  • Length: 1,094 feet
  • Passenger Capacity: 5,231 double occupancy; 6,762 max capacity

Costa Smeralda/Costa Toscana (Tie)

largest cruise ship that

These two ships come in at a tie for the eighth-largest cruise ship in the world. Built in 2019 and 2021, respectively, they both belong to Costa Cruises. And if the shape of the ship looks familiar, that’s because Costa is a sister line to Carnival. A similar design is used for Carnival’s largest ships, Mardi Gras, Celebration, and Jubilee. However, those ships come in just under the 185,000 gross tons seen with Smeralda and Toscana.

Both ships offer 13 pools and hot tubs, nearly a dozen restaurants and just under 20 bars and lounges. And if you like balcony views? There are 1,550 balcony rooms on each, providing plenty of options for the roughly 6,500 passengers that can sail at full capacity.

  • Gross Tonnage: 185,010
  • Length: 1,106 feet
  • Passenger Capacity: 5,224 double occupancy; 6,554 max capacity
  • Year Built: 2019/2021

P&O Arvia

largest cruise ship that

Taking the crown as the 10th-largest cruise ship in the world is Arvia from P&O Cruises. Measuring just under 185,000 gross tons, it offer a similar design to ships like Costa Smeralda and Carnival Celebration, but don’t think these ships are all the same.

For instance, Arvia features a unique Skydome area that is a pool area with retractable roof by day and an entertainment venue by night. It also features its own rum distillery onboard, meaning you can take home rum literally made on the ship. Kids will love the Altitude zone that features a ropes course, mini-golf, and more. There’s also Mission Control, a submarine-themed escape room.

All told, a reported 6,685 passengers can enjoy the ship at one time.

  • Gross Tonnage: 184,700
  • Length: 1,130 feet
  • Passenger Capacity: 5,200 double occupancy; 6,685 max capacity

The World's Largest Cruise Ship Is Coming in January—Here's What It's Like Inside

By Jessica Puckett

A Look Inside the World's Largest Cruise Ship Launching January 2024

The biggest thing to ever hit cruising is coming in January 2024, when Royal Caribbean’s Icon of the Seas —which will be the largest cruise ship in the world —will debut to passengers for the first time.

With capacity for nearly 10,000 passengers and crew, Icon of the Seas is billed as part all-inclusive resort, part theme park, and a massive destination unto itself . Clocking in at 250,380 gross tons and measuring nearly a quarter mile long (1,198 feet to be exact), the vast ship will sport a total of 20 decks, 18 of which will be accessible to guests.

The ship will be divided into eight different “neighborhoods,” each with their own distinct atmospheres, dining options, and activities. “ Icon of the Seas is truly what we call a white paper ship,” Anna Drescher, manager of architectural design, new building and innovation for Royal Caribbean group, said in a video statement . “The reason that we call it that is we start with a blank sheet of sketch paper, so it truly is starting fresh.”

In June 2023, the ship hit a major milestone when it completed its first sea trials outside the shipyard in Turku, Finland. Next up is the colossal new ship’s first voyage, slated to depart on January 27, 2024. It will sail roundtrip from Miami to the Caribbean islands of St. Kitts, St. Thomas, and the Bahamas.

The ship's typical seven-day itineraries include three at-sea days, so passengers have time to fully enjoy the endless choices of amenities on board. “We want guests to walk up to the ship and just have this moment of: I can’t believe that’s where I’m going ,” said Jennifer Goswami, the line’s senior manager of product development.

Here's a look at the enormous scale of the new ship and what to expect on board.

exterior and top deck icon of the seas

When it begins sailing, the Icon of the Seas will offer a total of 2,805 staterooms that can hold 5,610 passengers at double occupancy, or a maximum of 7,600 guests. Passengers can choose from a whopping 28 different room types, including Sunset Suites with wraparound balconies and Family Infinite Balcony staterooms with bunkbeds fit for a family of up to six.

balconies of the ultimate family townhouse

The largest suite on board will be the three-story, 1,772-square-foot “Ultimate Family Townhouse,” which comes with its own movie theater, ping-pong table, karaoke, and a slide between floors. It can sleep up to eight people and costs approximately $75,000 per week.

central park neighborhood icon of the seas

Among the eight "neighborhoods," or sections of the ship with distinct ambiance, are Central Park, which offers greenery and sidewalk cafes, and The Hideaway, which aims for a European beach club aesthetic. There's also The Suite Neighborhood, Surfside, Thrill Island, Chill Island, The Royal Promenade, and the Aquadome.

The ship's 2,350 crew members will also get their own neighborhood, complete with amenities like a gaming room and hair salon.

thrill island waterpark icon of the seas

Another superlative for Icon will be sporting the largest waterpark at sea. The park, called Category 6, features six different record-breaking waterslides, including the tallest onboard waterslide. There will also be a free-fall slide, plus a raft-style slide for four passengers to ride together.

Seven pools and nine whirlpools will be located throughout the ship, including the first infinity pool on a cruise ship to be suspended in the air. The Royal Bay pool, located on the 15th deck, will break the record for largest pool at sea, holding an astounding 40,000 gallons of water.

main dining room icon of the seas

Across the towering vessel, there'll be more than 20 food venues and 15 bars and nightlife experiences, including a sweeping three-level main dining room.

Among the options for grabbing a drink will be the line's first onboard swim-up bar, a walk-up Champagne bar, and a bar specializing in coffee cocktails like espresso martinis.

aqua theater icon of the seas

On the entertainment front, Royal Caribbean has hired 75 performers to titillate guests across three cavernous theaters. The Absolute Zero ice arena will feature shows with Olympic-level skaters, while the AquaTheater will combine the talents of divers, robots, and skateboarders.

In the Royal Theater, a 16-piece orchestra (the largest one at sea), will accompany shows like the Wizard of Oz.

In smaller venues throughout the ship, like the dueling piano bar, 50 live musicians and comedians will perform each night, making it possible for every type of passenger to find something that fits their style.

The 20 Biggest Cruise Ships in the World in 2023

By: Author Carrie Ann Karstunen

Posted on Published: March 1, 2022  - Last updated: January 6, 2023

The 20 Biggest Cruise Ships in the World in 2023

Cruise ships have been getting bigger—and adding lots of attractions that were unheard of just a few years ago. To help you pick which megaship is right for you, I’ve rounded up the 20 biggest cruise ships in the world in 2023.

Along with a ranking of the top 20 cruise ships by size , I’ve included important stats and unique features for each ship. If you’re considering sailing on one of the biggest cruise ships in the world, you’ll want to read this guide before you choose!

How do we determine the size of cruise ships for comparison?

Cruise ships can be measured by a variety of factors. You might assume that a ship’s size is determined by its length, weight, or even its passenger capacity.

But the size of a cruise ship is generally determined by gross tonnage —and (confusingly) that’s not a measurement of weight!

Gross tonnage, or GT, is a measure of the ship’s internal volume . To calculate GT, first a ship’s volume is calculated by measuring from keel to funnel to the outside of the hull framing. That number (in cubic meters) is then run through several mathematical formulas to determine GT. (I won’t go into all of that here, but if you’re interested the US Coast Guard has a simplified guide to measuring gross tonnage ).

The world’s 20 largest cruise ships in 2023

Currently, the top 20 biggest cruise ships have four sets of ties in the rankings, all between sister ships that share the same cruise line and class. So although we’ll start our list at #16, there are twenty ships in total!

Cruise fans will notice there are several new ships on the list this year. Have any of these newer ships bumped your favorites down in the rankings? Read on to find out!

16. (tie) MSC Seascape

largest cruise ship that

  • Cruise line: MSC
  • Year built: 2022
  • Gross tonnage: 170,412
  • Length: 1112 ft / 339 m
  • Max. beam: 135 ft / 41 m
  • Staterooms: 2270
  • Max. passengers: 5877
  • Passenger decks: 15

Just making this year’s list of the world’s 20 largest cruise ships, MSC Seascape is tied for #16. The second Seaside EVO class ship launched by MSC Cruises in just over a year, Seascape features a glam New York City vibe.

The ship’s four-story Atrium is at the heart of the action on board, and boasts a sparkling staircase set with 10,000 Swarovski crystals—the perfect spot for a photo op on formal nights !

But MSC Seascape isn’t all glitz and glamour—the family-friendly ship offers 13 pools and water features and more than 140,000 square feet (13006 m²) of public outside space. Kids will love Pirates Cove Aquapark , a play space with slides, a rope bridge, and plenty of water sprayers and dumping buckets to beat the heat.

Seascape is also the first ship to feature the new thrill ride Robotron , a robotic virtual rollercoaster ride perched on the top deck.

Foodie guests on MSC Seascape will enjoy the ship’s eleven restaurants, including a massive Market Place Buffet and several specialty dining venues grouped together at Chef’s Court .

16. (tie) MSC Seashore

largest cruise ship that

  • Year built: 2020 (launched 2021)
  • Max. beam: 134.5 ft / 41 m

Almost identical to her sister ship Seascape , MSC Seashore is tied for #16 on the list of the largest cruise ships. The first in the EVO subclass of MSC’s Seaside class ships, Seashore and her sister are larger than other ships in their class and offer expanded outdoor spaces.

As an EVO ship, MSC Seashore offers improved technology to increase efficiency and reduce her carbon footprint. The energy-efficient equipment includes an advanced wastewater purification system and Safe Air , a new sanitation system that eliminates viruses and bacteria.

Seashore was purpose-built for the American market, but still offers the European flair that MSC is famous for. Guests can enjoy a taste of Italy at the ship’s Venchi 1878 gelato bars , offering twenty flavors of the decadent frozen treat in flavors like tiramisù and stracciatella.

MSC Seashore also features a gorgeous aft infinity pool—one of the largest at sea—with luxurious submerged sunbeds. The spot is a tranquil adults-only oasis by day, but it comes alive in the evening as the setting for the always-popular Silent Disco .

15. (tie) MSC Bellissima

largest cruise ship that

  • Year built: 2019
  • Gross tonnage: 171,598
  • Length: 1,036.2 ft / 315.83 m
  • Max. beam: 141 ft / 43 m
  • Staterooms: 2,217
  • Max. passengers: 5,686
  • Passenger decks: 14

Tied for the fifteenth spot in the list of the world’s largest cruise ships, MSC’s Bellissima is as tall as thirteen double-decker buses!

Perfect for a family cruise, Bellissima offers a wealth of kids’ activities for children aged one through seventeen. Parents can track kids’ whereabouts on board via an RFID bracelet synced with MSC’s app. For adults who want to enjoy a leisurely meal, there’s the Happy Dinner program where the little ones are escorted to the kids club as soon as they finish eating!

MSC Bellissima is home to a thrilling Grand Canyon-themed waterpark with three waterslides—two racing tubes as well as a champagne bowl-style slide. The younger set will love the Aquaplay spray area, and guests of all ages can climb the Himalayan bridge, a rope course that crosses the ship high above the water.

Guests aboard Bellissima also have access to an electronic cruise assistant, similar to Siri or Alexa. A first in the cruise industry, Zoe —who speaks seven languages and adapts to each passenger’s preference—provides information and help booking shows, spa treatments, and shore excursions, as well as notifications of events and promotions.

15. (tie) MSC Meraviglia

largest cruise ship that

  • Year built: 2017
  • Staterooms: 2,244
  • Max. passengers: 5,655

When MSC’s Meraviglia entered service in 2017, she was the sixth-largest cruise ship in the world—but has since fallen to #15, tied with her newer sister ship Bellissima .

The namesake of the Meraviglia class of cruise ships, she was the first to offer an expanded dining experience with fourteen restaurants, including a whopping four complimentary main dining rooms. Celebrity chef Carlo Cracco was enlisted to improve the quality of the ship’s cuisine.

On Meraviglia entertainment options abound—the Broadway Theatre hosts six unique shows each cruise, along with the Carousel Lounge where you can experience Cirque du Soleil at sea. The crew also puts on an impressive amount of activities and events, so there’s always something to do on a sea day .

The ship’s Amusement Park has a full-size bowling alley, 4-D cinema, F1 simulators, an arcade, as well as a sportplex that becomes a disco spot for young cruisers in the evening.

14. (tie) MSC Virtuosa

MSC Virtuosa, one of the largest cruise ships

  • Year built: 2020
  • Gross tonnage: 181,541
  • Length: 1,087.4 ft / 331.43 m
  • Max. beam: 160 ft / 50 m
  • Staterooms: 2,421
  • Max. passengers: 6,334

MSC’s ship Virtuosa , built in 2020, is one of the newer offerings by the Swiss-Italian cruise line and is tied for number fourteen on our list of the world’s biggest cruise ships.

Virtuosa offers five pools in total, plus a water park with three waterslides, so water babies of all ages can spread out and enjoy the fun. The pools can accommodate over a thousand guests at a time!

If relaxing with a cocktail is more your style, stop by and see Rob the bartender at Starship Club . He’s the first humanoid bartender at sea, and speaks six languages!

Cruisers can also wander the Galleria Virtuosa —the pretty indoor promenade with restaurants and shops features an arched ceiling with the longest LED dome at sea , presenting an ever-changing light display.

14. (tie) MSC Grandiosa

MSC Grandiosa, one of the world's biggest cruise ships

  • Staterooms: 2,632
  • Max. passengers: 6,761

Tied for number 14, Grandiosa was the first vessel in MSC’s Meraviglia-Plus class , later joined by her sister ship MSC Virtuosa .

With 200 more staterooms than previous MSC ships, Grandiosa has expanded the number of accessible cabins on board, and added groups of up to three connecting staterooms as well as new family balcony cabins. Some spacious family staterooms can sleep up to twelve!

Grandiosa also has some innovative environmental features, including systems to reduce nitrogen oxide emissions by 80%, and sulfur emissions by 97%. She has a fuel-efficient hull and can run on shore power when docked.

Fun fact: Grandiosa ‘s godmother is Italian screen legend and longtime MSC ambassador Sophia Loren. She actually holds that honor for most of MSC’s fleet!

13. Mardi Gras

Emeril’s Bistro 1396 , created in partnership with celebrity chef Emeril Lagasse (Carnival’s new Chief Culinary Officer ), serves up New Orleans-style Creole dishes.

The Grand Central Atrium reinvented the central area of the ship, with a larger space featuring bars, cafés, and shops with aerial performances overhead.

Celebration pays homage to her homeport of Miami with the 820 Biscayne zone, named after the cruise line’s first headquarters. The zone will feature the Deco Deli and 820 Bar , serving up Cuban sandwiches and tropical drinks.

Younger guests can check out Space Cruisers , a new program offered in partnership with the Kennedy Space Center. Kids age 2 to 11 will have the opportunity to try NASA-inspired activities tailored to their age group.

8. (tie) Costa Smeralda

largest cruise ship that

Tied for eighth place is Costa Smeralda , a favorite of sustainability-minded cruisers. Smeralda was the first in Costa’s fleet powered by liquefied natural gas (sister ship Toscana now also shares this feature), a fuel source that reduces the ship’s environmental impact.

Other eco-friendly features include LED lighting throughout the ship, an onboard desalinization plant that sustainably harvests onboard water directly from the sea, and systems that recover the engines’ heat to reduce energy use.

Costa Smeralda earned the coveted Green Plus notation from RINA, only awarded to the most environmentally friendly cruise ships.

P&O UK ‘s newest ship Arvia is also the cruise line’s largest, and debuts at #7 on the 2023 list of biggest cruise ships. An Excel-class ship like Iona , Arvia is similar but boasts some key differences.

Like her sister, this ship also features a Sky Dome over the pool area—but Arvia ‘s is retractable to allow for alfresco swimming, dining, and entertainment when the weather is right.

Arvia is home to the fleet’s first swim-up bar , complete with plenty of in-water seating, allowing guests to order and enjoy a cocktail right in the pool.

The new ship debuted several new restaurant concepts, including Green & Co featuring Mizuhana , featuring fish and plant-based cuisine. Also new are Roast at The Quays for traditional British lunches and the 6th Street Diner , an American-style diner serving breakfast,brunch, and dinner.

  • Length: 1094 ft / 333.3 m
  • Max. beam: 154 ft / 47 m
  • Staterooms: 2626
  • Max. passengers: 6762

With the debut of MSC World Europa in December of 2022, MSC Cruises now has a whopping seven ships on the list of the top 20 biggest cruise ships in the world—the most of any cruise line!

The Geneva-based company has been working diligently to expand the fleet and MSC’s newest cruise ship is a whopper of a vessel.

The ship is an astounding 21 decks high (there’s a deck 22, but cruise superstition skips deck 13), four decks taller than the largest cruise ship in 2023. Sixteen of those decks are passenger-accessible.

Much like the megaships offered by Royal Caribbean, MSC World Europa is divided into several districts that contain similar offerings—a must-have on any gargantuan cruise ship. Guests can visit the adults-only Zen district for a bit of calm, or the Family district with ten kids’ facilities offering fun for little cruisers and their grownups.

Ranking among the top ships with the most water features at sea, World Europa offers six pools and 14 hot tubs , along with an aquapark featuring multiple waterslides.

MSC World Europa is also the line’s first LNG-powered cruise ship —and the biggest liquefied natural gas powered cruise ship in the world! This cleaner alternative to traditional marine fuel significantly reduces carbon, sulfur, and nitrogen oxide emissions.

5. Allure of the Seas

largest cruise ship that

  • Cruise line: Royal Caribbean
  • Year built: 2010
  • Gross tonnage: 225,282

Royal Caribbean’s Allure of the Seas ranks as the fifth largest cruise ship in 2022. She’s the second (and smallest) of the Oasis-class ships.

Allure of the Seas features seven themed “neighborhoods”—the Royal Promenade, Central Park, Entertainment Place, Boardwalk, Pool and Sports Zone, Vitality at Sea, and the Youth Zone.

With a ten-deck-high zip line and the interactive H2O Zone waterpark, Allure of the Seas is a favorite ship for adventurous cruisers of all ages.

4. Oasis of the Seas

largest cruise ship that

  • Year built: 2009
  • Gross tonnage: 226,838

Number four is Oasis of the Seas , the first of the namesake Oasis class, and the oldest ship to make the top 15 list. Built in 2009, she was then the largest cruise ship in the world, and the first to have a maximum capacity of over 6000 passengers!

Oasis of the Seas may be an older ship, but she doesn’t look like one! In 2019 she had a $165 million transformation that brought the ship up to date.

Entertainment abounds on this ship, from the splashy Aqua80 show in the AquaTheater to Music Hall , a live music venue with plenty of floor space for dancing. Or try one of the four onboard water slides including the ten-story-high Ultimate Abyss .

3. Harmony of the Seas

largest cruise ship that

  • Year built: 2016
  • Gross tonnage: 226,963
  • Length: 1,188.1 ft / 362.12 m

Enjoy a cocktail at Bionic Bar , where one of two robot bartenders can shake you up the perfect martini. But don’t worry, the ship’s 13 other bars and lounges are staffed by friendly humans.

Or play a lively game of glow-in-the-dark laser tag to battle for control of Planet Z —when the ship’s ice rink is temporarily transformed into an alien world, of course.

MIAMI (AP) — The world’s largest cruise ship — the size of almost four city blocks — is set to begin its maiden voyage Saturday as it leaves from the Port of Miami.

Royal Caribbean’s Icon of the Seas runs nearly 1,200 feet (365 meters) from bow to stern.

The ship, which is leaving South Florida for its first seven-day island-hopping voyage through the tropics, was officially christened Tuesday with help from soccer legend Lionel Messi and his Inter Miami teammates.

At a glance

The Icon of the Seas:

  • can carry up to 7,600 passengers and 2,350 crew members

The ship has:

  • six waterslides
  • seven swimming pools
  • an ice-skating rink
  • more than 40 restaurants, bars and lounges

“Icon of the Seas is the culmination of more than 50 years of dreaming, innovating and living our mission – to deliver the world’s best vacation experiences responsibly,” Royal Caribbean Group President and CEO Jason Liberty said earlier this week. “She is the ultimate multigenerational family vacation, forever changing the status quo in family travel and fulfilling vacation dreams for all ages on board.”

The ship sets sail as Royal Caribbean’s cruises are having a moment online. Since December, the company’s 9-month “Ultimate World Cruise” has captivated — and confused — a following of avid watchers on social media.

Millions are following the journey through the eyes of the passengers, as they live and post their lives aboard a vessel they’ll be on for nearly a year. If it sounds like a reality show, that’s exactly what some watchers have turned it into.

When the Icon of the Seas was first revealed in October 2022, the ship spurred the single largest booking day and the highest volume booking week in Royal Caribbean’s then 53-year history, according to the cruise line.

The Icon of the Seas is divided into eight neighborhoods across 20 decks. The ship includes six waterslides, seven swimming pools, an ice skating rink, a theater and more than 40 restaurants, bars and lounges. The ship can carry up to 7,600 passengers at maximum capacity, along with 2,350 crew members.

It is powered by six dual-fuel engines, which can be powered by liquefied natural gas (LNG), a fuel alternative that the Cruise Lines International Association says reduces sulfur and greenhouse gas emissions. However, some environmentalists worry LNG-powered ships increase methane emissions . Other say that vacationers generate eight times more carbon on a cruise than they do on land.

Royal Caribbean says every kilowatt used on the Icon of the Seas “is scrutinized for energy efficiencies and emission reductions.”

Key Takeaways

  • Icon of the Seas is the largest cruise ship in the world, with 18 passenger-accessible decks, eight different neighborhoods and 2,805 staterooms.
  • Think of Icon of the Seas as an all-in-one adventure vacation contained on a ship. Young families and energetic travelers will enjoy it most.
  • Itineraries originate from Miami , sail to destinations around the Caribbean and include a stop at Royal Caribbean's private island , Perfect Day at CocoCay.

If you have any degree of interest in traveling or cruising, chances are you've heard the buzz around Icon of the Seas. Another record-breaking ship by Royal Caribbean International , Icon of the Seas debuted on Jan. 27, 2024, as the largest cruise ship in the world. It is epic in every sense, featuring 18 cruiser-accessible decks and stretching 1,196 feet from bow to stern.

With greatest-of-all-time soccer player Lionel Messi as the ship's godfather, the Icon of the Seas is truly iconic. Messi brought the entire Inter Miami team along for the opening ceremony and the big reveal of the team's new Royal Caribbean-sponsored jerseys. I was fortunate enough to attend this star-studded ceremony as part of the press preview sailing in the days leading up to the ship's grand debut to the public. It was everything I thought it would be and more, and nobody could have been more appropriate than Messi to send this ship on her maiden voyage.

Boarding a ship of this size can seem overwhelming, but not when you understand the layout. Icon of the Seas is broken up into eight distinct neighborhoods: AquaDome, Central Park, Thrill Island, Chill Island, Royal Promenade, The Hideaway, Suite Neighborhood and Surfside, a neighborhood built for young families looking for nonstop fun and kid-approved eats and treats.

In addition to these public areas, there are 2,805 staterooms spread across 12 decks. Icon of the Seas' capacity maxes out at 7,600 passengers and 2,350 crew members, but with the plethora of public spaces and variety of things to do and see, you can choose your own adventure without encountering more crowds than you want to.

Icon of the Seas itinerary

During its inaugural 2024-2025 cruising season, Icon of the Seas offers seven-night eastern or western Caribbean adventures from Miami, stopping at a variety of tropical destinations. All sailings include a stop at Royal Caribbean's award-winning private island, Perfect Day at CocoCay, in the Bahamas . Other destinations include Basseterre, St. Kitts & Nevis ; Roatan, Honduras; and Cozumel, Mexico .

During the 2025-2026 cruising season, new destinations will include Puerto Plata, Dominican Republic ; San Juan, Puerto Rico ; Labadee, Haiti; Costa Maya, Mexico; and Charlotte Amalie, St. Thomas (part of the U.S. Virgin Islands ). All sailings will originate from Miami.

No matter your Icon of the Seas itinerary, you'll visit beautiful places – but you can expect to feel torn about spending any time off the ship, because it's just that jampacked with things to do.

Royal Caribbean International's newest ship, Icon of the Seas.

Who should sail on Icon of the Seas?

Icon of the Seas appeals not so much to a demographic as to a psychographic; you're going to need to be someone who likes to live life in all caps. Royal Caribbean set out to create "the world's best vacation" contained on a ship, so Icon of the Seas is for anyone who would enjoy the combination of a beach trip, a resort stay, a water park adventure and island-hopping.

Fun-loving travelers and families with kids of varying ages will do best on this ship; it feels a little bit like Disney World with over-the-top everything and a truly massive sprawl. Older travelers who prefer a more quiet, refined experience may want to opt for a less kid-friendly ship. Still, even couples without children will find plenty of fun adult-friendly things to do and romantic places to tuck in.

The Royal Promenade can be quite loud and buzzy, but simply relocating to another onboard neighborhood can completely shift the vibe. Also, keep in mind that the ship really is huge, and walking from end to end can be a hike, so those with limited mobility or endurance might want to look into a smaller ship.

Icon of the Seas prices are high in its opening season, but cruisers with big dreams and small budgets can expect rates to drop by the time the next ship in the series debuts.

Royal Caribbean International's newest ship, Icon of the Seas.

The stateroom

With a ship this overstimulating, it's imperative that your stateroom is a haven. Luckily, Icon of the Seas offers peaceful rooms, many of which feature ocean or Central Park neighborhood views. Cruise ship accommodations are stereotypically compact – even cramped – but the floor-to-ceiling panoramic windows in Icon of the Seas' cabins (with the exception of the windowless interior rooms) lend an airy, open feel. The cabin layouts are also optimized to provide the maximum amount of storage, floor space and comfort.

Stateroom decor is mildly nautical- and tropical-themed, with calming hues that mimic the scenery outside your window (think blues, beiges and whites). High-tech elements include smart TVs, LED mirrors and the ability to control many aspects of your room from an app.

My husband and I stayed in an Ocean View Large Balcony Stateroom, a 204-square-foot refuge from the hustle and bustle of the ship (the balcony adds another 65 to 70 square feet). This room type can sleep up to four people with a sofa bed for one or two; the room also features twin beds that convert to a king bed for couples.

My husband is 6 feet, 3 inches tall, and we were comfortable in our room, even though our quarters included a large bed, a bathroom, a sofa and a desk. We loved sitting on our private balcony and watching the deep blues of the Atlantic Ocean flow by.

If money is no object, the Ultimate Family Townhouse – an over-the-top eight-guest, three-story pad with a private whirlpool on the balcony, three bathrooms, a slide that connects the second and main levels, an in-suite cinema, a dining room and a kitchenette – looks epic. But keep in mind, it costs nearly $100,000 for the week.

The Sunset Corner Suites (about one-fifth of the cost of the Ultimate Family Townhouse, but still expensive) are also pretty sweet, with a wraparound balcony and a bed facing the sea.

Luckily, not all rooms break the bank; with four main stateroom categories (suite, balcony, ocean view and inside) and 28 subcategories, there's something for everyone.

Royal Caribbean International's newest ship, Icon of the Seas.

Best amenities on Icon of the Seas

It's almost impossible to run out of things to do aboard Icon of the Seas.

For thrill-seekers, the largest water park at sea – Category 6 – features the Frightening Bolt (the tallest waterslide on a ship) and the Pressure Drop (the first open freefall waterslide on a cruise vessel).

If you've tired of the seven swimming pools, six waterslides, laser tag, mini-golf, rock climbing wall, escape room, sports courts, outdoor decks, theater, spa and all-day programming, simply take a stroll down the Royal Promenade for Las Vegas -style people-watching. The Royal Promenade has 15 restaurants, bars and lounges, as well as a Starbucks that seems to have a line no matter what time you go. The neighborhood feels a bit like a shopping mall … if a shopping mall had floor-to-ceiling ocean views made possible by the world's largest kinetic art sculpture.

The Pearl, a feat of engineering, is one of the most unique aspects of the ship's design. This art piece is actually a load-bearing structure supporting three decks, but it looks and feels like an interactive art experience designed solely for the enjoyment of guests. The multisensory immersive structure has 3,000 kinetic panels and moody ever-changing lighting. It is one of the first things guests will see when they walk on board, as it stretches from the Royal Promenade up to Central Park.

My husband and I spent most of our time at the FlowRider surf simulator – his favorite amenity – but we made sure to leave time for Taylor Swift trivia at Spotlight Karaoke and the superhuman stunts of the Aqua Theater show, a must on any Icon of the Seas voyage. The ship even has a massive ice arena called Absolute Zero for ice skating (the 20-minute sessions are complimentary) and impressive shows.

We also loved lounging in The Overlook Bar & Pods, an area at the very front of the ship (behind the AquaDome) that features two levels of floor-to-ceiling wraparound windows. It felt airy and open, which can't be said about many cruise ship interiors.

Best dining venues on Icon of the Seas

There are more dining options aboard Icon of the Seas than you can fit in on a seven-night cruise – but you can give it the old college try. Thirteen of the dining venues are complimentary, while 14 are specialty restaurants (which cost extra; fees vary). There are also 18 bars and lounges.

The best meal we experienced on the ship was at the Chops Grille specialty eatery. When we spotted Royal Caribbean CEO Jason Liberty and a group of bigwigs at a table next to us, we knew we were in the right place. We loved sitting outside and enjoying the breezes of Central Park while we chowed down, but you can eat indoors for an elegant steakhouse experience and a view of the open kitchen and butcher's display, which shows off specialty cuts like high-grade wagyu and bone-in tomahawks.

While I'd never turn down a swanky steak dinner, grabbing quick poolside bites at El Loco Fresh and indulging in some food hall-style grazing at AquaDome Market were equally enjoyable. We also had no complaints eating several meals at Windjammer, the classic complimentary cruise ship buffet.

Even though we don't have children, we stopped into Surfside Bites for a very kid-friendly meal, complete with soft serve ice cream cones from Sprinkles (because no cruise is complete without soft serve). We didn't try anything from the open-air, lemonade stand-inspired Lemon Post bar, but its menu of cocktails and mocktails looked delicious.

And since you're on vacation, be sure to check out the milkshake bar Desserted, where the sugary creations are as photo-worthy as they are decadent. They're worth the upcharge.

Best excursions on Icon of the Seas

Depending on what's on your Icon of the Seas itinerary, you may be able to book activities like snorkeling, scuba diving, tropical jungle adventures, visits to Mayan ruins, volcano hikes, rainforest zip lining, relaxing beach days or cultural immersion tours.

Note that Royal Caribbean features the same options on many of its other Caribbean cruises; none of the excursions on offer are exclusive to Icon of the Seas.

Because our press preview sailing only visited Perfect Day at CocoCay, we did not experience any of the shore excursions. Royal Caribbean's private island in the Bahamas was plenty of fun, even though we didn't plan anything in advance.

If we had made plans, we would have liked to check out the Up, Up and Away tethered hot air balloon, which wasn't running that day, and the overwater cabanas at Coco Beach Club, which were all booked. Thrill Waterpark (which features the tallest waterslide in North America), Oasis Lagoon (the largest freshwater pool in the Caribbean) and the adults-only Hideaway Beach are other highlights of Perfect Day at CocoCay.

Overall impressions of Icon of the Seas

Royal Caribbean seems to be focused on superlatives. It has the biggest, best, tallest, largest and most of everything – especially when it comes to Icon of the Seas. If you like jampacked, adventurous vacations that squeeze a lot of adventure and relaxation into one memorable week, Icon of the Seas is probably for you.

While I love seeing Royal Caribbean push the limits of what cruises can be, the ship may almost be too big for some. It's an all-out Vegas-esque vessel that feels more like a floating city; you will probably forget (more than once) that you're not on dry land.

That's not necessarily a bad thing – if Icon of the Seas looks fun to you, it probably will be – but my husband and I tend to gravitate more toward authentic, immersive, on-the-ground cultural experiences when we travel. While Icon of the Seas is a lot of things, it's not that. We had a fantastic time and have already started planning a future Royal Caribbean cruise with a group of friends and family, but we also sympathize with the anticruisers of the world. Vacationing does not a traveler make.

Still, the shows are entertaining, the service is attentive, the music is jamming, and the architecture and design are incredibly impressive. I have no real complaints and suspect that most cruisers will have the time of their lives on Icon of the Seas – exactly as the minds at Royal Caribbean envisioned when they dreamed up this iconic ship.

GEORGE TOWN: The world's largest privately-owned residential cruise ship has docked in Penang for the next two days.

State tourism and creative economy committee chairman Wong Hon Wai said the cruise, dubbed "MS The World," would stay at the Penang cruise terminal for two days before departing for Langkawi on Tuesday (May 14) night.

He said the ship docked in Penang at 2pm on Sunday (May 12) and would depart at 11pm on Tuesday (May 14).

"This cruise serves as a lavish retreat for individuals and their families as it sails across the world's seas," he said.

"This extraordinary vessel houses 165 ultra-luxurious apartments, which arrived in Penang after it departed its last port of call at Koh Phi Phi, Thailand.

"Its next destination will be Langkawi," he said in a statement on Sunday (May 12).

Wong said its arrival was a momentous occasion in the state, marking a significant milestone for Penang.

"It solidifies our position as a premier destination for luxury maritime travel.

"Situated strategically in Southeast Asia, Penang stands out as a prime destination for cruise liners traversing the region.

"Serving as a key port city, the Swettenham Pier Cruise Terminal in George Town showcases Penang's dedication to providing world-class facilities and services tailored to cruise tourists," he said.

MS The World is a private residential cruise ship operated like a condominium complex, with large apartments that can be purchased. Residents from many countries can live on board as the ship travels.

Some residents choose to live on board full-time, while others visit periodically throughout the year.

'Utopia of the Seas': World's second-largest cruise ship to set sail from Florida's Port Canaveral this summer

PORT CANAVERAL, Fla. - A new Royal Caribbean cruise ship will soon set sail from Port Canaveral in Florida – just in time for the summer!

The cruise line's Utopia of the Seas will make its debut in the Orlando area on July 19.

The ship comes on the heels of Royal Caribbean’s unprecedented launch of the world's largest cruise ship, Icon of the Seas , in Miami earlier this year.

Utopia is considered the second-largest cruise ship in the world, measuring 1,188 feet long, 211 feet wide, and featuring 18 decks to accommodate 5,668 guests.

Officials said the ship will be the first Oasis Class ship tailored exclusively for weekend getaways. It will offer 3 and 4-night vacations to tropical destinations such as Nassau, Bahamas, the cruise line's private island, Perfect Day at CocoCay, and Cozumel, Mexico, according to Royal Caribbean's website .

The ship will feature:

Royal Railway – a first-of-its-kind immersive train car restaurant

Caribbean-inspired tiki bar called Pesky Parrott

More than 40 restaurants, bars and lounges

Five swimming pools and three waterslides

Two casinos for a Vegas-style vacay

A FlowRider surf simulator, rock climbing wall, mini golf, an indoor ice arena

The longest dry slide at sea

Entertaining shows across air, ice, water and stage

  Utopia will join her sister ships, Wonder of the Seas and Voyager-class Adventure of the Seas, establishing Port Canaveral as the homeport for two of the world’s largest three ships.

Endangered 44-foot whale likely killed by massive cruise ship, dragged into NYC port: experts

A massive cruise ship likely struck and killed an endangered whale before sailing into the East River Saturday morning — and there’s no telling how long the dead mammal was dragged by the boat before it was discovered, according to marine experts.

The 44-foot adult female Sei whale was found as the MSC Meraviglia docked at the Port of Brooklyn, a spokesperson for MSC cruises confirmed.

The unlucky cetacean was removed from the 19-deck ship and towed to Sandy Hook, New Jersey, Tuesday for a necropsy, said National Oceanic and Atmospheric Administration fisheries spokesperson Andrea Gomez — but emphasized it is too soon to tell whether or not the whale was dead before impact.

Rob DiGiovanni, the founder and chief scientist of the Atlantic Marine Conservation Society, however, told The Post it was more than likely that the “interaction with the vessel contributed to her death.”

“It looks like she was eating,” DiGiovanni said, indicating she was a healthy whale with relatively fresh food in her stomach.

The hulking Meraviglia — the same ship that rescued 24 distressed Cuban migrants from a boat off the coast of Florida last year — weighs 171,600 gross tonage and stands 214 feet tall.

When and where the whale was struck remains a mystery, but Sei whales are typically observed in deeper waters far from the coastline, according to NOAA.

They are one of the largest whale species and are internationally protected, with vessel strikes listed as one of the biggest threats to its dwindling population.

The body was “pretty decomposed,” DiGiovanni revealed, but said that does not help professionals lock down a timeline of its death.

The temperature of the water, especially on the higher side, can accelerate the decomposition process by days.

The tragic event is unfortunately not uncommon, according to DiGiovanni, but it’s nearly impossible to track just how often it occurs because the whales could sink to the bottom of the ocean floor after being struck.

Ship staff or guests also might not even notice a striking, considering just how large cruise vessels stand, making even the world’s largest mammal look like an ant.

Such strikes could contribute to the unusual mortuary event in the New York Bight Apex — the waters from Fire Island to the Manasquan Inlet in New Jersey.

Starting in 2016, humpback, Mackey and North Atlantic Right whale deaths skyrocketed from one to three per year to 12 to 14 per year, DiGiovanni said.

The shocking death surge is a tragic side effect of whales flocking to Big Apple waters in higher numbers per year, creating a Catch-22 situation.

While some stay year-round, the amount of whales enjoying the East River jumps as spring rolls around.

“We start to see increases in whale sightings now, so we urge boaters to use caution in the waters,” DiGiovanni said, encouraging ship captains to consider the “Slow: Children at Play” mentality when taking on the open seas.

NOAA reiterated this sentiment: “Mariners operating along the US East Coast are encouraged to slow their vessel speed, stay alert, and report any sightings of right whales or any dead, injured, or entangled whales.”

Cruise ship arrives at New York City harbor with dead whale caught on bow

The 44ft-long whale corpse was an endangered sei whale, which will now be examined to determine how it died

A cruise ship has journeyed into New York City’s harbor bearing a gruesome cargo in the form of a huge, dead whale sprawled across its bow.

The incident happened on Saturday, according to local US media reports , and the event is being held by some as further evidence of the unfortunate impact on sea life that large vessels can have.

The 44ft-long whale corpse was an endangered sei whale and was caught on the ship’s bow when it arrived at the Port of Brooklyn, according to a National Oceanic and Atmospheric Administration fisheries spokesperson, Andrea Gomez.

The boat involved was the Meraviglia, which docked in New York before sailing on a journey to ports in New England and Canada. It is owned by Geneva-based MSC Cruises .

“We immediately notified the relevant authorities, who are now conducting an examination of the whale,” officials with the cruise line said in a statement, who added that the company had regulations in place to avoid collisions with whales and other animals at sea.

“We are deeply saddened by the loss of any marine life,” the statement said.

The whale is now the subject of a necropsy to try and determine how it died, notably if it was already dead when hit by the cruise ship. Sei whales are one of the largest whales and are a protected species.

I'm a CEO who ran my company from a cruise ship for a month. It requires a lot of discipline, but I'd do it again.

  • Tony Fernandes, CEO of UEGroup, managed his company from a cruise ship for 21 days.
  • Fernandes experienced challenges with slow internet and communication but found workable solutions.
  • Despite the hurdles, he finds value in being offline at times and plans to continue cruising.

Insider Today

This as-told-to essay is based on a conversation with Tony Fernandes, a 60-year-old founder and CEO of UEGroup based in San Francisco, about his experience working remotely on a cruise ship. It's been edited for length and clarity.

My wife and I are in the post-kid, post-pet phase of our lives. Our kids have gone off to college and we had a beloved dog and house rabbits that have passed away. After they passed, that really opened up a window for us to travel — and we did — but extended travel is new for us.

In November, I embarked on a trip where I spent several weeks leading my company from a cruise ship with my wife. We ultimately circumnavigated the globe on two different cruises and with air travel. Leaving California, we went through Europe, Singapore, Thailand, Malaysia, and Japan.

It's been a cool experience. But I found that while working on the ship , you do need some discipline — especially on a 21-day cruise.

You have to create a time for work and a time for play

We didn't realize it, but when we upgraded our internet, it upgraded our drinks package. So, it turned out we could get bottles of Moët & Chandon Champagne for free.

We had a couple of lunches and dinners where we enjoyed Champagne , but we also developed a rhythm where we had work time and playtime. It wasn't rigid — but there were times when my wife, who does finance at UEGroup, and I knew we had to get things done.

Related stories

Working can set you apart from people who are on vacation. That doesn't mean you can't work in your bathing suit or have a beer before you start your work, but it puts you on a slightly different footing than some of the other people on the cruise.

Expect very slow internet service

One thing I didn't realize prior to the trip was that the cruise ship had only one satellite connection shared by thousands of people. The internet was oppressively slow at times.

For our next long trip, I'm looking into getting a data satellite phone so I can put an antenna on my patio facing the right direction for the satellite. I've still got to figure it out, but there were times when it was really important for us to communicate, and we couldn't.

We're now very mistrustful of statements the cruise lines make about the quality of their internet. For example, we upgraded our Internet, but it turned out the cruise line's definition of upgrading was that we could have more than one device, not that there was any better speed or reliability. You've got to read the fine print about how they define an upgrade.

I would also recommend asking what kind of download and upload speeds to expect.

Create a backup plan for meetings and other communication challenges

Internet access can be unpredictable even with research and planning ahead, so we had backup people for important meetings back at the office. If we weren't able to show up, there was someone prepared with the slide deck. I can't say it didn't create awkward moments at times — and it is one of the downsides — but you can plan for it the best you can.

When my wife was dealing with a bank and needed to get a two-factor authentication code without working SMS, there wasn't much she could do. So, that was a challenge as well.

At some points, I was forced to go ashore and buy SIM cards to leverage local cell service, but this requires research. Depending on the country there might only be one cellphone service that works there, or you might be able to get SIM card brands that work for a larger area.

Being offline can end up being a good thing

I find it hard to be offline, but because the connectivity was so bad sometimes, it just forced it to happen. We were in the middle of nowhere, and it wasn't going to change. In a way, being offline was good because I could just tune out.

My wife and I plan to cruise more in the future and even recently bought a home in Portugal near a cruise port that we're going to commute to using cruises as much as possible.

When we did the math, taking a cruise from California to Portugal was less than two business-class air travel tickets. Plus, you get meals, entertainment, and no jet lag — it seems like the way to go.
