Some 35 minutes by boat from Providenciales, sitting all alone on a 1,000-acre island with three miles of white-sand beach, Parrot Cay attracts a seriously moneyed clientele who care, more than anything, about its exclusivity and its spa. Parrot Cay is not exactly monastic: the long list of celebrity visitors has included Jennifer Garner and Ben Affleck (they got married here), as well as Paul McCartney, Julia Roberts, Jerry Seinfeld, and Liam Neeson. But the spa, COMO Shambhala Retreat, is so successful at projecting a holistic way of life that a sense of peace and harmony embraces the entire resort. The central garden-view and ocean-view rooms, three minutes’ walk from the beach, are acceptably chic, but the beachfront suites and villas are knockouts, and the handful of private homes for rent, some owned by celebrities (Christie Brinkley, Donna Karan), are in the fantasy category. The food, by a chef whose résumé includes a Michelin star, and the service, performed by private butlers for some room categories, are of commensurately high standards.
