Allure of the Seas is one of the world's largest and most revolutionary ships with neighbourhoods - Royal Promenade, Central Park, Boardwalk (nostalgic seaside piers), AquaTheater, climbing walls, and the world's first onboard Carousel and Zipline. The Allure of the Seas refurbishment is scheduled over a 58-day drydock to the tune of $165 million dollars in May 2020.
