A dolphin cruise is for watching from the boat. A snorkel trip adds a swim stop, most often at Shell Island, and many include dolphin watching, so you rarely need both. The park ferry only takes you to the island; the beach day is up to you. Each guide compares the operators, what's included and the cancellation rules. Prices are the lowest we found on November 1, 2026, from the operators, Expedia and Viator.
