I used an AAA discount for POFQ this past January, the first time in a decade. It was the best rate I could get (20%), because WDW was offering a 5 - 15% discount for the time I was staying. It's been hard to get a good discount on FQ, I think because it is in demand? I booked the discount directly through WDW, and I was asked to show my card when I checked in.
