Unwind at a AAA 4-Diamond resort on the largest private island in the Florida Keys for $139 per night with a 20% discount on spa treatments.
 
The top-rated Hawks Cay Resort slices 40% off current rates for stays of two nights or longer, Sunday-Thursday through Dec. 23. Weekends are discounted by 20%.

Soak up the sun in one of six pools, including a saltwater lagoon. Or, take a diving, snorkeling or fishing trip from the resort's full-service marina.

Situated between Key Largo and Key West, the resort is less than a two-hour drive from Miami. 

Looking to stay longer? The hotel extends a fourth-night free offer on select dates. While it is based on regular rates (rather than the $139 nightly special), it cuts the effective nightly rate to as little as $120 midweek.

Note: There is a $25 resort fee per night (plus tax). It covers all gratuities (except at the bars and restaurants), wireless Internet, parking, and access to the kids club and fitness center.

Not available on: Oct. 13, 21-26; Nov. 3, 13, 23-25; Dec. 1 (however, these dates might be available at higher rates)
