The Florida mall is only a couple of miles away. It is a big mall with Sears, JC Penny, etc. as anchor stores. I don't know that there are any 'deals' there, but it is a nice place to look around and kill some time.
The airport itself has finished the big remodel, and added several new stores. (The food court is GORGEOUS!) Eyeball it when you arrive -- you may want to plan to spend your time there, instead.
Yes the airport sounds good - however we are from Canada and do not have a Target here and the malls have stores that we do not have. With 3 girls a mall is part of the vacation (unfortuntely not to my husband - but that's just too bad!! )
