It might not be as well known as the neighboring islands of St. Vincent, St. Lucia, or Martinique, but Mustique offers natural beauty to compete with any of them — and the Firefly Mustique is the place to stay to enjoy it. This luxury retreat offers five different rooms — many spacious enough to be considered suites elsewhere — each offering Caribbean views, comfortable beds, breakfast, lunch, and dinner, complimentary snacks for sunset, a beach basket with towels, beach games, masks and snorkels, and even a plunge pool in the largest, most secluded room. There's also a restaurant on site, a bar with the best sunset views on the island, a driver to take you to the beach, and a complimentary cell phone to use when you're ready to come back to the room (or if you just need more rum).
