This December, Royal Caribbean International will once again make waves on the cruise vacation scene with the debut of the world’s next largest and most innovative cruise ship, Allure of the Seas. As did sister-ship Oasis of the Seas, the arrival of Allure of the Seas will bring an unprecedented array of brand new features and onboard amenities, including one of Broadway’s longest-running and most recognizable theatric productions, Chicago: The Musical, which will headline in the ship’s main theater. Reprising the lauded at-sea debut of Hairspray aboard Oasis of the Seas, Allure of the Seas’ Amber Theater will join an illustrious list of venues, such as the Ambassador Theater in New York City and the Cambridge Theatre in London’s West End, that have raised the curtain on the award-winning musical.
