Gladden Private Island

The Belize Barrier Reef “In an overconnected world, seclusion has become even more of a benchmark of luxury,” said Mark Ellwood in Bloomberg.com. Enter Gladden, a single villa on a mangrove-fringed island a few miles off the southern coast of Belize. Though the two-bedroom villa can accommodate four guests, most bookings come from couples who want a break from the rest of humanity. Guests never have to see another person if they don’t want to: The staff of four stays on a nearby islet, and whenever they venture over, small warning lights flash in every room. gladdenprivateisland.com; from $2,950 a night
