5. An Oddball Day
You don’t need to fly to the Caribbean to have an underwater adventure. Just a half-hour west of the Hamptons, at Atlantis Marine World in Riverhead, kids can spend a half-hour in a cage face-to-face with ten sharks, a 300-pound turtle, seven-foot-long moray eels, stingrays, and exotic fish. For $155 a person, visitors over 12 years old can earn major bragging rights by getting into scuba gear and dunking into a two-story water tank filled with real, live sharks.
