No, the Thrill Waterpark at Royal Caribbean's private island, "Perfect Day at CocoCay," is not free; it requires a paid admission ticket. As of 2026, prices for a full-day pass typically range from $89 to $189 USD per person, depending on the ship, the season, and the specific sailing date. This pass grants you access to the massive "Daredevil’s Tower" (home to the tallest waterslide in North America), the "Splash Summit" family slides, and the Caribbean’s largest wave pool. While the waterpark has a high price tag, Royal Caribbean does provide plenty of free alternatives on the island, including Chill Island, Harbor Beach, the massive Oasis Lagoon freshwater pool, and the "Splashaway Bay" kids' water play area. For 2026 travelers, it is a high-priority "pro-tip" to book your waterpark passes in the Royal Caribbean app as early as possible, as the price often jumps significantly as the cruise date approaches or if the island is expected to be at high capacity with multiple ships docked at once.
