The Biggest Royal Caribbean Ships
Royal Caribbean makes the biggest cruise ships in the world and so many people want to know what is the largest Royal Caribbean cruise ship.
Royal Caribbean’s largest ship is Icon of the Seas. This is the biggest cruise ship in the world, and the first of the Icon class of ships. It is 1,198 feet long, has 20 decks in total, and a capacity for 7,600 guests and 2,350 crew.
And it’s the longest ship in the world too, though only by around 10 feet.
The previous record holder wasn’t Wonder, but actually Harmony of the Seas – but only by mere inches. Icon’s extra 10 feet makes it comfortably the biggest cruise ship in the world. Though she already has sister ships on order which will likely break that record.

Royal Caribbean Ship Classes By Size
Royal Caribbean International has eight classes of ships. Each class has between one and five sister ships.
Each of the sister ships are very similar in design, although they may have different amenities on board, which is why some ships are heavier than their sisters.

Are the bigger ships better than the smaller ships?
Whether you prefer the larger ships in the Royal Caribbean fleet or the smaller ships is all a matter of personal preference. Some people love large ships because there is so much to do on board.
We cruised on Allure of the Seas for seven nights and didn’t get time to see or do everything on board. However, others might find the biggest ships a little too over-facing, preferring something a little more serene.
The biggest ships tend to be more expensive than the smaller, older ships. This means that in effect, you’re paying extra for the facilities that larger ships have. If you plan to spend most of your time relaxing by the pool or exploring ashore, then there’s no point paying more for a ship with facilities that you won’t use.
Even the small to medium size ships are still pretty big. We cruised on Mariner of the Seas for four nights and were never short of activities on board. For a short sailing like this, the mid-sized ships on the fleet are ideal.
But, who cares what I think? To find out which ships are actually the best, I collated all of the reviews from Cruise Critic, TripAdvisor and Cruiseline.com.
