There are also some Port Adventures on Castaway Cay as well as other activities that come with a fee. You can rent equipment for fun activities such as bikes, snorkel equipment, or aqua trikes for a nominal fee. You can also book some activities for a fee.

While Disney’s private island, Castaway Cay, includes your lunch at Cookie's BBQ and access to most beaches, there are several "extra" costs to factor into your 2026 budget. You must pay for alcoholic beverages, specialty sodas, and any snacks or ice cream outside of the main buffet. Port Adventures are a major expense, with activities like parasailing (~$140), glass-bottom boat tours (~$60), or stingray interactions (~$60) requiring a fee. Rentals are also extra: a bicycle for an hour is roughly $19, and a "Getaway Package" (snorkel gear, float, and bike) is about $54. If you want a truly luxury experience, private beach cabanas can cost over $800 per day and are famously difficult to book. Finally, the "Buy the Seashore" and "She Sells Sea Shells" shops sell island-exclusive merchandise that cannot be bought on the ship, so you'll want your SeaPass card ready for souvenirs and tropical sundries.
