The featured Broadway musical on Royal Caribbean's Symphony of the Seas in 2026 is the Tony Award-winning hit "Hairspray." This full-scale production is a staple of the ship's entertainment lineup and is performed in the Royal Theater. The show is an original Broadway production that follows Tracy Turnblad's journey in 1960s Baltimore, blending catchy music with a powerful message about race relations and social change. In addition to "Hairspray," the Symphony of the Seas offers several other "headliner" shows, including the high-diving spectacular "Hiro" in the AquaTheater, the ice-skating show "1977," and the original theater production "Flight: Dare to Dream," which chronicles the history of aviation. Guests are strongly encouraged to book their showtimes via the Royal Caribbean app as soon as they board (or even before), as these performances are extremely popular and often reach capacity quickly. "Hairspray" remains one of the most beloved shows in the fleet, specifically noted for its high production value, professional cast, and the infectious energy that makes it a highlight for cruisers of all ages.
