Hello KarenNY- We booked using USA code in Feb. Like you, my ressie conf. only showed the awd #. Does your ressie # end with US1? When I viewed my ressie it was for a higher price. I called Avis customer service- 1 800 352 7900 m-f 7:30-7:30. I didn't specify that I used the USA code, I only asked for a confirmation of my correct lower rate. After a couple of calls and faxes to Avis, they did confirm my lower rate on their computer( mine still showed a higher rate). Once at the counter there was no problems at all, no questions were asked and I was done in under 5 min. Did you sign up for a wizard #? Once you do you can print out an e-coupon to give to the counter rep. for an add. 5.00 off per day, up to 5 days. You can add this coupon onto any discounts you already have. They give you the discount when you return the car, not when you pick it up.( It is noted on your receipt).
Good luck
