I have used the code for quite some time. Most airport locations have gotten hip to it and will ask you for ID. I have NEVER been asked for ID to use that AWD code at an Avis location that is not located at an airport. And recently, on several occasions, I have been successful at using the code at airport locations by accompanying my drivers license and credit card with a neatly folded $20 bill. I place the twenty between my license and CC and hand it to them (before they have a chance to ask for the ID) and say "I know I am supposed to have a Florida ID, but I don't have it with me. I am hoping you can overlook that this one time." Not only has it worked every time so far, but every time I have been upgraded to a FAR SUPERIOR car than the one I booked. I can tell you that for longer rentals (more days) the $20 is well worth it. Even for a two day rental, some of the other codes on here are $118 for an economy car, where the FL code is $49. Worth a crisp twenty? It is to me!
