I realize this is a really old thread but didn't want to create a new one for such a simple question.
If the reservation and hilton honors account are in my name, but my wife is staying with me...is her AAA membership good enough for the discount? I do not have my own. She will be present at check-in and can show her card if need be. Didn't know if the different names on the AAA account and hilton account would be a problem.
