biggest cruise ship to date

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

By Jessica Puckett

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.

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.

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.

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.

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.

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.

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.

Largest Cruise Ships

See here the world's largest cruise ships list (including vessels under construction ) owned by the best cruise line companies . This article is also integrated with our ship dimensions , passenger capacity , and old cruise ships surveys.

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.

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

Daily Correspondent

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.

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.”

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.

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

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

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

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

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

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

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

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)

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

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 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

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

• 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

• 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

• 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

• Year built: 2017

World's Largest Cruise Ship Sets Sail for the First Time in Initial Sea Trial — See Photos!

Royal Caribbean's "Icon of the Seas" is slated to embark on its maiden voyage out of South Florida in January 2024

Royal Caribbean's record-breaking Icon of the Seas is drawing closer to its debut in January 2024 after completing its first phase of sea trials in Europe.

Set to be the world’s largest cruise ship and the company's first Icon-class ship, the vessel has been under construction at Meyer Turku shipyard in Finland, according to an official release .

The cruise will offer vacationers the world’s largest waterpark at sea, dubbed Category 6 and featuring six water slides. Icon of the Seas also offers a "resort getaway," a "beach escape," a theme park and over "40 ways to dine, drink and be entertained," according to the company.

Inside, it will feature a one-of-a-kind accommodation: the "Ultimate Family Townhouse," which Royal Caribbean describes as a three-story "sprawling adventure-filled pad" with an in-suite slide, a karaoke station, and hidden areas to discover.

The ship's 20 decks will include Royal Caribbean's first-ever dueling piano bar, eight "neighborhoods," the largest pool at sea and experiences for thrill-seekers like Crown's Edge, described as "a fear-inducing challenge that’s part skywalk, part ropes course, part thrill ride and an all-out test of your courage."

The ship weighs in at an estimated 250,800 tons and measures close to 1,200 feet long. It also holds about 5,610 passengers and 2,350 crew members, according to CNN .

Over 450 specialists have run four days of preliminary tests on the ship’s main engines, bow and propellers, as well as checking noise and vibration levels, a release shared.

"Between preparations and the trials, the important step in the journey to bring  Icon  to life involved more than 2,000 specialists, hundreds of miles traveled, four 37- to 67-ton tugboats and more than 350 hours of work," according to the release.

All of that will prepare the cruise for its second round of sea trials later this year, ahead of its debut out of South Florida in January 2024.

The Icon of the Seas will set sail from Miami on 7-night Eastern and Western Caribbean vacations all year round, where passengers can visit popular tropical destinations like the Bahamas, Mexico, St. Maarten and Honduras, as well as Royal Caribbean's private island, CocoCay.

At a press panel earlier this year, Royal Caribbean International President and CEO Michael Bayley described the ship as “literally the best-performing new product launch we’ve ever had," according to CNN.

Royal Caribbean will be ousting themselves from the top spot. It's Wonder of the Seas is currently the world’s largest cruise ship.

U.S. News has compiled this roundup of new cruise ships that have just set sail or are scheduled to launch later in 2023 and in 2024, plus a preview of new ships coming in 2025 and beyond. The list includes everything from expedition and luxury yacht-style vessels to reimagined ships and megaships – plus the debut of a brand-new cruise line.

Norwegian Cruise Line: 2025 and beyond

The third Prima-class ship is expected to be approximately 10% larger than the first ship in the class, Norwegian Prima (143,535 gross tons). The following ships for the line are anticipated to be even larger, with the fifth and sixth Prima-class vessels (debuting in 2027 and 2028) weighing as much as 171,000 gross tons.

Celebrity Cruises

Celebrity's fifth Edge-class ship will be more eco-friendly, thanks to the addition of a new tri-fueled engine model and the capacity to store three different kinds of fuel, including methanol. The effort toward net-zero emissions and more sustainable cruising is a partnership between Royal Caribbean, the French shipyard Chantiers de L'Atlantique and the technology firm Wärtsilä. A debut date for this ship has not yet been announced.

A cruise line for every type of traveler: How to choose the right one for you

• Cruise lines have their own identities and areas of focus, and some lend themselves more to certain vacation types than others.
• Royal Caribbean International, Norwegian Cruise Line and Disney Cruise Line are solid options for families.
• Aurora Expeditions, Celebrity Cruises and Silversea Cruises offer trips with a spirit of exploration at their core.

No matter what kind of vacation you're planning , there's likely a cruise for you.

Whether you want to spend your trip kayaking and scuba diving or prefer to lounge on a sun deck sipping a cocktail, cruise lines have a wide range of offerings. But not every line or ship is right for every passenger.

Cruise brands have their own identities and areas of focus, and some lend themselves more to certain vacation types than others (amenities can also vary from ship to ship within the same line). Here's what to know:

Best cruise line for families

◾ Royal Caribbean International ships have an array of onboard offerings for kids and adults. For example, the line's most recent addition, Icon of the Seas, has been billed as the ultimate family vacation .

The vessel – the largest cruise ship in the world – has an entire neighborhood designed for young families, a large water park and activities ranging from a FlowRider surf simulator to Crown's Edge, where guests can walk more than 150 feet above the ocean. The line's Bahamas private island, Perfect Day at CocoCay, offers plenty of thrills and places to chill , too.

◾ Norwegian Cruise Line also offers a range of activities like free-fall dry slides, go-kart tracks, and high-caliber stage shows. Disney Cruise Line draws on a huge catalog of stories to bring magic to life on the water, with character appearances, themed dining and special events like Marvel Day at Sea .

◾ Carnival Cruise Line and MSC Cruises also cater to families, and Princess Cruises and Holland America Line are solid options for multigenerational travelers. Mainstream cruise lines generally have kids clubs that are included in the fare, as well.

Best cruise line for adventure and expeditions

Adventure seekers may want to consider expedition ships and lines that offer sailings to less common destinations such as Antarctica .

◾ Aurora Expeditions offers a range of activity-centric itineraries, including Zodiac boat outings, kayaking, snowshoeing and more. Celebrity Cruises, meanwhile, has a vessel designed  especially for the Galapagos Islands .

◾ Operators like HX (formerly Hurtigruten Expeditions) , Lindblad Expeditions and Silversea Cruises also offer trips with a spirit of exploration at their core.

Best cruise line for letting loose

◾ Virgin Voyages offers adults-only sailings and a unique onboard atmosphere with its immersive Scarlet Night celebration and innovative performances . There is also no main dining room or buffet, with a focus on a variety of different food and drinks instead.

▶◾ Guests can also find parties on other lines, such as Carnival . But the length of the sailing and the time of year play a role in a cruise's vibe. Spring break cruises, for instance, may be rowdier than times when school is in session.

◾ Parties can take different forms, too. Cunard Line , for example, hosts formal gala nights .

Best cruise for rest and relaxation

Upscale cruise lines can lend themselves to a more relaxed and pampering experience. Guests are less likely to encounter rock-climbing walls or ice-skating rinks but will find amenities like pools and carefully curated dining. The following operators are all in that category:

◾ Silversea

◾ Regent Seven Seas Cruises

◾ Oceania Cruises

◾ The Ritz-Carlton Yacht Collection

However, even on mainstream lines, guests can often get away from the bustle of the ship in onboard spas and adults-only areas. Luxe ship-within-a-ship concepts like Norwegian's The Haven or MSC's Yacht Club can also offer a more intimate, laid-back experience.

Best lines for river cruising

River cruising tends to be small-scale and destination-focused.

▶◾ European river itineraries from lines like AmaWaterways, Uniworld Boutique River Cruises and Viking often stop at a mix of marquee and less-visited ports, so guests aren't fighting crowds the whole time.

▶◾ In the U.S., American Cruise Lines offers a diverse selection of itineraries, from sailings on the Columbia and Snake Rivers to round-trip cruises from Washington, D.C. Viking also has a ship purpose-built for the Mississippi River .
