A very recent addition to Royal Caribbean's array of onboard activities are water slides. Unlike other cruise lines, Royal Caribbean did not offer large water slides on its cruise ships until fairly recently.
Harmony of the Seas, Liberty of the Seas and Adventure of the Seas offer similar water slides known as, "The Perfect Storm." These slides offer a fast and thrilling ride that is certain to be a hit with families.
In addition, Harmony of the Seas features an additional champagne bowl slide that swirls guests around as they make their approach to the end of the ride. Liberty of the Seas has the Tidal Wave slide, which has guests boarding a raft and sliding up a near vertical wall for a very fun effect.
Water slides are available mostly during the day, and free for guests to enjoy as many times as they like.
