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 International has been delivering innovation at sea for over 50 years. Each new class of ship has been considered an architectural marvel featuring the latest technology and guest experiences. Royal Caribbean currently makes the biggest cruise ships in the world. The cruise line continues to revolutionize vacations with itineraries to more than 270 destinations in 72 countries on six continents, including Royal Caribbean’s private island destination in The Bahamas, Perfect Day at CocoCay, the first in the Perfect Day Island Collection.

The Icon of the Seas’ tonnage is five times that of the Titanic. The ship is 1,198 feet long and features 20 decks, with a capacity for 7,600 guests and 2,350 crew.
Are the bigger ships better than the smaller ships?
When it comes to deciding between Royal Caribbean ships, size does matter. While the larger ships may offer more amenities and activities, the smaller vessels can be just as exciting. Large and small ships offer an array of features that will keep guests entertained during their voyage, depending on what they are looking for in a cruise experience.
This ultimately comes down to personal preference and the cruise you are taking. For example, a family Caribbean cruise with kids will likely want a complete waterpark and many pools. At the same time, an adult-only cruise to Alaska might be more about the destination and less about the extensive ship amenities.
