A153700
Much discussion has been posted here about this code. Here is my experience:
I have used a variation of this code on my last ten rentals with absolutly no hassles at all. The variation: A153720.
While it is still a Avis Employee discount code, my belief is that is a Cendant Employees discount code. Cendant is the parent company of Avis & Budget.
As with any code that may be questioned, USE AT YOUR OWN RISK!
