Have you guys seen
this? Gives some real insight into using Avis corporate codes. I'm pretty sure the AWD referenced in the article is A113400, which is for all state of Florida employees, not just Dept. of Mgt. Svcs. as stated in the post.
A113400 is well-known to provide great discounts and has quite a history in this thread. Be aware that if you use this code and run into a manager or agent who's a stickler for the rules, it could cause you some trouble - unless you actually work for Florida, of course.
