+1 I just gave up and went to avis
So here's a question... I never actually add the CDP when i make my reservations. I have never had an issue with CDP's (I also am over 25). I leave it blank and just put in the PC for the amount of certs I am going to use. If I go to LAX, but haven't entered in the CDP which is on the cert, are you saying I will have an issue?
