Showcasing 180 feet of azure beach in gated Bay Colony’s On the Strand, the glamorous dream world in Naples is one of Florida’s trophy estates. Its splendor beguiles, however, for its real purpose in life is to promote fun in the sun. That it does on a monumental scale. Embracing some 15,941 square feet, it is endowed with everything from stunning party venues and six dreamy suites to a plush media lounge and fourth-floor gym commanding the Gulf. Two other settings are unforgettable: a Paul Wyatt connoisseur’s wine room for 16,000 bottles and a resortlike pool terrace with a spa and Tuscan pizza oven—a stage that is set for starlit evenings along the romantic beach.
