No, admission to the Thrill Waterpark is not included in the standard cruise fare for Royal Caribbean's "Perfect Day at CocoCay." While a large portion of the island—including the Oasis Lagoon (the Caribbean's largest freshwater pool), Chill Island, South Beach, and the shipwreck-themed Captain Jill's Galleon—is complimentary, the Thrill Waterpark requires a separate paid admission pass. This pass grants you access to the 13 record-breaking waterslides (including Daredevil's Peak), the wave pool, and the adventure pool. Prices for these passes are dynamic and can range from $89 to $189 per person depending on the ship and the season. Guests who purchase a pass can enter and exit the waterpark as they please throughout the day using their SeaPass card. If you are looking for free water fun, the complimentary "Splashaway Bay" and "Captain Jill's Galleon" provide plenty of slides and water cannons for children at no extra cost, making the paid waterpark an optional upgrade for those seeking high-adrenaline thrills.
