Exclusive to Princess Cruises passengers on Eastern, Southern and Western Caribbean itineraries since 1992, Princess Cays -- located 70 miles east of Nassau, on the southern tip of the island of Eleuthera, one of what's known as the Bahamas' "Out Islands" -- comprises 40 acres that offer more than 1.5 miles of white-sand beaches, food, water sports and even shopping.
Although Princess uses a section of the island, the rest of Eleuthera is inhabited by a population of about 11,000 residents. The cruise line does run excursions to some of the smaller villages outside the complex, such as Rock Sound (known for its bottomless blow hole) and the picturesque fishing village of Tarpum Bay. (Although it's Eleuthera's best-known tourist draw, Harbour Island, with its tony shops and restaurants, is too far away to visit.)
But, for most people, Princess Cays remains a guilt-free beach day, where you can rent water toys, sign up for a snorkel excursion or simply hang out in a private cabana. Bring water shoes, as the shoreline by the water can have sharp rocks and coral fragments.
