If you talk to some of the more independant car rental companies there are some really good deals to be had out there. I had booked a car with Dollar, and a couple days before my reservation I called around and asked companies if they had any last minute type rates. The customer service rep at Priority One Auto Rental agreed to price match my full size with their entry level car (an Audi A4)..and of course, they dont charge the airport fee since they arent on site, and they dropped the car off and picked it up at MCO for me!
