Splash about in D-Boat, a retired oil tanker turned party boat and water park, moored just offshore from Antigua. Careen down a waterslide, jump on a trampoline or swing off a rope out into the sea. Soak up the sun and enjoy lunch with an open bar of selected beverages. In lieu of the snorkeling tour nearby, upgrade to include a trip to top-rated Stingray City, where you can pet and feed southern rays in clear shallow water. This family-friendly experience includes round-trip ferry transport from Jolly Harbour and the boat ride to and from Stingray City.
