Kiss a bottlenose dolphin, swim with stingrays, snorkel with tropical fish in a reef lagoon, or just take it easy riding a winding lazy river at Discovery Cove. An all-inclusive tropically landscaped park with a daily visitor limit of 1,000, it’s one of Orlando’s most popular — and costly — attractions. Since guests must be at least 6 years old to participate in a dolphin encounter, some families opt to save this special spot until their children enter the grade school years. Advance reservations are required, and you can book up to six months in advance.
