Are you looking for the most activity-packed, megaresort-like Royal Caribbean cruise ships at sea? If so, you’ll want to get on one of the biggest Royal Caribbean cruise ships.
These ships are, by nature, the Royal Caribbean ships with the most pools, waterslides and other top-deck activities, as well as the most onboard restaurants, bars and showrooms. They have the biggest casinos and spas among ships in the Royal Caribbean fleet, as well as the largest number of cabins and suites — and the most variation in cabin and suite types.
With room for more than 6,000 passengers, the biggest Royal Caribbean ships are truly massive resorts like you’d find at landlocked destinations such as Orlando and Las Vegas. If you’re in the “bigger is better” camp when it comes to a resort experience, these are the Royal Caribbean ships for you.
Royal Caribbean doesn’t only operate massive vessels, though. The Miami-based cruise giant also operates quite a few relatively small cruise ships that carry just 2,000 or 3,000 people and have a much more intimate feel. In some cases, these vessels are just half or one-third of the size of Royal Caribbean’s biggest ships. These ships, notably, have far fewer top-deck activities and interior venues than the biggest Royal Caribbean cruise ships.
The smallest Royal Caribbean cruise ships are best for vacationers who like a more intimate, less crowded resort experience.

What is the biggest Royal Caribbean ship?
The biggest Royal Caribbean cruise ship is Icon of the Seas. Measuring 248,663 gross tons, it’s not only the biggest Royal Caribbean ship but also the biggest cruise ship ever built by any line. It’s loaded with more bars, restaurants, theaters and top-deck attractions than you’ll find on any other ship at sea.
Icon of the Seas is the first in Royal Caribbean’s new Icon Class of ships. A second ship in the Icon Class, Star of the Seas, will debut in August 2025.
How big is Icon of the Seas?
At 248,663 gross tons, Icon of the Seas is about 5% larger than Royal Caribbean’s second-largest ship, Utopia of the Seas. Icon of the Seas can carry up to 7,600 passengers — a new record for a passenger ship.
The bigger passenger capacity is partly due to the ship’s greater focus on family travelers. Icon Class ships were built with many more cabins with plenty of extra bunks to accommodate families with children. They also have more amenities geared toward families. The ships include a new-for-the-line outdoor “neighborhood” called Surfside, which is dedicated to families with young children.
What is the smallest Royal Caribbean ship?
The smallest Royal Caribbean cruise ship is Grandeur of the Seas. Measuring just 73,817 tons, it’s just one-third of the size of Icon of the Seas.
Grandeur of the Seas dates to 1996, a time when cruise ships were built far smaller than they are today and with far fewer amenities and dining venues. At nearly 30 years old, it’s the oldest vessel in the Royal Caribbean fleet and probably will be phased out sometime in the next few years.
Except for a rock climbing wall, Grandeur of the Seas has none of the “gee whiz” Royal Caribbean top-deck attractions — such as skydiving simulators and giant water parks — found on the newest Royal Caribbean vessels. For the most part, its top deck is lined with pools, whirlpools and sunning areas, as is typical for ships built in the 1990s.
That said, Grandeur of the Seas has a loyal following among Royal Caribbean fans who prefer smaller and more intimate ships.
Royal Caribbean has hinted that it might build a new series of smaller ships that could replace Grandeur of the Seas and other older, smaller vessels in the line’s fleet.
Are bigger Royal Caribbean ships coming?
Royal Caribbean currently has four new cruise ships on order, all of which will be among its biggest cruise ships ever.
The ships on order include three more vessels in the line’s Icon Class, meaning they will be similar to Icon of the Seas in size and amenities. They’re on order from a shipyard for delivery in 2025, 2026 and 2027 respectively. The first two, respectively, will be named Star of the Seas and Legend of the Seas; the third is currently unnamed.

Royal Caribbean also has one more ship in its popular Oasis Class series on order for delivery in 2028.
Launched in 2009 with the debut of Oasis of the Seas, the Oasis Class vessels have dominated the world of mega-size cruise ships since that year. When the class began rolling out, the vessels were around 40% bigger than the next-biggest cruise ships, and they have continued to be among the largest and most amenity-laden ships in the world ever since.
The new Oasis Class vessel, which hasn’t yet been named, is expected to be roughly the same size as Utopia of the Seas, Royal Caribbean’s second-biggest cruise ship, but smaller than Icon Class ships.
What’s the difference between bigger and smaller Royal Caribbean ships?
Royal Caribbean’s biggest ships have room for many more onboard venues and attractions than Royal Caribbean’s older ships. That makes them more alluring for vacationers who prefer a big, bustling megaresort experience to a stay at a smaller resort.
On Royal Caribbean’s biggest Oasis Class vessels, for instance, you’ll find three separate main pool areas, a kiddie splash zone, surfing simulators, a miniature golf course, a basketball court and even a zip line. And that’s just on the top decks. Inside the vessels, you’ll find more lounges, bars, restaurants and shops than you can imagine — plus huge casinos, spas and theaters with Broadway-style shows. They even have indoor ice skating rinks.

Royal Caribbean’s smallest ships are one-half to one-third smaller than the Oasis Class and Icon Class vessels and lack many of the above features. They have a much more intimate feel, at least in the pantheon of relatively big mass-market ships, and they hold far fewer people. While Oasis Class and Icon Class ships can hold more than 5,400 passengers at double occupancy, the line’s four oldest vessels (known as the Vision Class) are designed to carry only about 2,000 passengers at double occupancy.
Royal Caribbean’s smallest ships are a good choice for someone who wants to try Royal Caribbean but isn’t eager to travel with huge crowds. The smallest ships in the Royal Caribbean fleet appeal to a subset of Royal Caribbean fans who prefer more intimacy in a cruise vessel and don’t mind giving up some onboard amenities to get it. They are also often less expensive on a per-day basis for cruisers.

Additionally, because of their size, the smallest Royal Caribbean ships can operate itineraries to places that aren’t as easy for big ships to visit. Not all ports in the world can handle ships the size of Icon Class vessels.
