Vegas meets the tropics in the island's biggest, splashiest casino, a vision in neon and glitz. It's 21,000 square feet of gaming fun, from roulette to poker to some 410 slot machines. High rollers have their own VIP tables. Upstairs is the urban-style dance club Tantra. It's part of the Sonesta Maho beach resort complex, with a number of restaurants and shops nearby.
