Sorry but I don't for the life of me understand why anyone and especially AAA should think that you can apply more than one discount to a reservation. I have AAA and I have AARP both of which will give me a discount at most hotels but I could not call and book a room and apply both AAA and AARP discount too it,
and if they have a weekend special or something at a hotel, I cannot book it and have them also take off the AAA discount. it is always one or the other.
