Royal Caribbean’s biggest ship
Many people want to know ‘what is the largest Royal Caribbean cruise ship?’ Royal Caribbean’s largest ship is Symphony of the Seas. This ship is the biggest cruise ship in the world in 2020.
However, a new ship, Wonder of the Seas is currently under construction and is scheduled to launch in the autumn of 2021. Wonder of the Seas will be almost 2,000 tonnes heavier than Symphony of the Seas and become the new biggest cruise ship in the world. However, Wonder of the Seas will have a slightly lower maximum guest capacity than sister-ship Symphony of the Seas.

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.
