Yes, Symphony of the Seas is a prominent member of Royal Caribbean's Oasis Class. Launched in 2018, it was the fourth ship in the class and held the title of "World's Largest Cruise Ship" until 2022. Like its sisters Wonder and Icon (the latter being the first of the newer Icon Class), Symphony features the trademark "seven neighborhoods" design, including Central Park with 20,000 living plants and the Boardwalk with its iconic AquaTheater. In 2026, Symphony of the Seas remains a flagship of the Royal Caribbean fleet, measuring 1,188 feet long with a gross tonnage of 228,081. It accommodates up to 6,680 passengers and is famous for its "Ultimate Abyss" slide and the "Bionic Bar" where robotic arms mix cocktails. While the newer Icon Class ships are technically larger, the Oasis Class—and Symphony in particular—remains the industry gold standard for family-focused "mega-ship" cruising.
