Holland America Line’s Half Moon Cay has been ranked “Best Private Island” by Porthole Cruise Magazine for 17 years running and is located on Little San Salvador Island in the Bahamas. (The island must remain 98% undeveloped as an international bird sanctuary.) The Cay’s 700-acre lagoon allows guests to feed stingrays and enjoy various water sports, a children’s aqua park and a buoyed personal watercraft course. The new Lobster Shack will offer Caribbean dining and drinks. Other features include private beachside cabanas with private butler service, showers and misters and eco-tours by glass-bottom boat.
