if you go to the budget website and click on "programs" it gives a bunch of info. i just joined a few weeks ago and it is free. orlando has a fastbreak counter service, so you still have to go to the counter but i think they have a "fastbreak" line seperate from everyone else. i also just noticed that if you join fastbreak they offer "upgrade benefits". wonder what that means! here is some info from their website.

Fastbreak Choice
Fastbreak Choice locations, available at most major US airports, provide the easiest way to rent a car. Simply confirm your reservation at the kiosk in the lot, select a car of your choice from your designated area, show your driver's license at the exit booth, and hit the road.
Fastbreak Counter
At Fastbreak Counter locations, show your driver's license to the Fastbreak counter agent, get your keys, and you're on your way.
Rapid Return and upgrade benefits also apply when you use Fastbreak.
Rapid Return is available at most major US airports - when you return your car, we'll print a receipt for you right in the lot. It's a perfect match with Fastbreak!
