Whatever you do, MAKE SURE YOU CAN GET AN AFFORDABLE CAR RENT (if you need one) BEFORE you pay for your flight if you're going someplace like PIE, Punta Gorda or even SFB. These airports have suddenly grown from very low levels thanks to Allegiant, and supply/demand on the limited car rents can swing very unfavorably at times as a result (or even sell out). Customers used to big airports with plenty of supply like MCO and TPA have been in for a rude awakening.
