Need travel advice quick!

I have two vouchers for AirTran that I must use by Feb. 29, or they expire. Aside from the vouchers, I don’t have much money.

Will be leaving from Atlanta, GA. I don’t mind cold weather destinations, but my wife hates the cold. Can’t think of any other preferences.

Any advice on a quick 4 to 7 day vacation for me and the Mrs.?

From checking out Air Tran’s destinations, how about San Juan, anywhere in FL (Daytona, Jax, Miami, WPB, Sarasota), Costa Rica, or Cancun? There’s a lot to choose from.

We don’t have passports, so Mexico and Central America is out. Puerto Rico and U.S. Virgin Islands is a thought, though. Thanks.
