Yes, Harmony of the Seas, one of Royal Caribbean's massive Oasis-class ships, features a dedicated ice-skating rink known as Studio B. This multi-purpose venue serves as a high-tech theater for professional ice shows, such as "iSkate 2.0," where world-class skaters perform intricate routines under dazzling lights. However, during various designated times throughout the cruise, the rink is opened to passengers for complimentary open-skating sessions. The ship provides all the necessary equipment, including skates and helmets, at no extra charge. It is important to note that for safety reasons, participants are required to wear long pants and socks while on the ice. Because sessions are popular and capacity is limited, guests are encouraged to check the "Cruise Compass" or the Royal Caribbean app to find specific "open play" times and arrive early to secure a spot. This unique feature remains a marvel of modern engineering, maintaining a frozen surface even as the ship sails through tropical Caribbean waters.
