Yes, I tried 3x times with the CC numbers and code from the back. I used it last night to make a purchase also and it works. No idea why it won't go through.
Guess I will just take my midsize with the Continental discount.
My DH could not sign up using his vis cc from his credit union. For some reason, it comes up as a debit card, even though it clearly is a visa credit card. This happened on the alamo site with quick silver as well. He was able to use our disney visa card for both sites though.

The code is under the Alamo Hot Deals. Hope it helps you.
