For $80 per person, per night, escape to an all-inclusive Jamaican resort -- complete with four restaurants, six bars, three pools, a four-story water slide, and water sports.

Here's how this deal works: Pay $120 per night for May-June (including Memorial Day) and get the third night free, slicing the effective nightly rate to $80.

Or come July 2 - Aug. 31 (including July Fourth) for an effective $83 per night when visiting for three nights. The free night still applies on longer stays.

Prices at the adults-only SuperFun Beach Resort & Spa cover:

• All food, snacks, and alcoholic and nonalcoholic drinks
• Activities such as windsurfing, kayaking, snorkeling and glass-bottom boat rides
• Daily and nightly entertainment
• Prepaid taxes and fees; no tipping is allowed at the resort

The resort overlooks the beaches of Jamaica's north coast, about an hour and a half from the Montego Bay airport. Transfers can be added for $20 per person roundtrip.

Bonus: This third-night-free special is available on visits in September and October, too. Plus, this is part of a larger Caribbean sale that includes SuperFun's sister brand of Breezes Resorts & Spas; resorts are discounted up to 35%.
