Royal Caribbean is a family cruise line, and as such, there are some great aqua parks for kids and their parents to enjoy together. These aqua parks have different names, but they all incorporate a large splash pad area with plenty of geysers, water cannons and spraying water fountains.
Freedom class ships and Oasis of the Seas and Allure of the Seas feature the H2O Zone, which is a multi-colored splash area that looks almost like a progressive art form, until you see all the water spraying in every direction. There is even a swirling pool that kids can enter and turn-about to their heart's content.
Royal Caribbean re-imagined the aqua park concept with its latest creation, Splashaway Bay. Available on Harmony of the Seas, Liberty of the Seas and Majesty of the Seas, this area features slides, water cannons, waterfalls and more in an "aquatic adventure park" for kids of all ages. Royal Caribbean describes Splashaway Bay as, "a vibrant waterscape for kids and toddlers with sea creature water cannons, winding slides, a gigantic drench bucket and a multi-platform jungle-gym to keep everyone entertained for hours."
On Radiance class ships, there is a small water slide and splash pool for young children to enjoy.
Due to public health regulations, children in diapers, swim diapers, pull-ups or who are not COMPLETELY toilet trained are not allowed in the pools, whirlpools or H2O zone. Otherwise, kids are free to use the aqua parks as much as they like.
