Update (Dec. 14, 2011, 5:56 p.m. ET): Due to popular demand, the following dates are now sold out: Jan. 3-7. Rooms are still available at slightly higher rates on these dates. 

Unwind at a AAA 4-Diamond resort on the largest private island in the Florida Keys for $129 per night.
 
At 50% less than comparable hotels, the top-rated Hawks Cay Resort trims rates over the following dates:

• Jan. 3-9, 15-17, 22-31
• Feb. 1-2, 5-7, 12

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 fifth-night free offer on select dates Feb. 13  - April 30. Although it is based on regular rates (rather than the $129 nightly special), it cuts the effective nightly rate by as much as 20%.

Note: There is an additional $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.
