Mary’s Boon Beach Resort & Spa A fixture since the 1970s, this simple 37-room boutique is hidden in plain sight right next to the airport. The grounds are lush, and there’s a restaurant and small spa, but the real standout is its “backyard:” the white-sand sweep of Simpson Bay, which feels as if it’s all your own. In short, this is a classic beach hotel that’s one of the Caribbean’s best beach bargains. Book Mary’s Boon Beach Resort.
