The largest Royal Caribbean ship is the Symphony of the Seas, which measures 228,081 gross tons. Symphony is 1,188 feet 1 inch in length (362.12m).
She is very close in size to her sister Oasis Class ships (Harmony of the Seas, Allure of the Seas and Oasis of the Seas).
Symphony of the Seas has a capacity of 5,518 passengers at double occupancy, or 6,680 passengers if at maximum capacity.
Symphony offers plenty for guests to do onboard, such as the Ultimate Abyss, waterslides and FlowRider surf simulators. Dining is major component to a cruise on Symphony, with choices of complimentary and specialty dining, including Hooked Seafood, Playmakers Sports Bar & Arcade and El Loco Fresh.
While not confirmed, the next Oasis Class ship is very likely to be the next biggest Royal Caribbean ship, as each new Oasis Class ship has been slightly larger than the previous one. Wonder of the Seas will debut in 2021.
