The offers can also differ from region to region. I work with a AAA TA in the Carolinas, but I live in MA which is AAA Southern New England. And we booked our trip in January last year because it was AAA month and the 2 regions had 2 different offers...neither of which we could take advantage of.
So far, I know that the Carolinas offer for Disney Month is a (small) gift card when you book the new promotion that is coming out on Jan. 3rd (the same that is currently available to Disney Visa cardholders.) So it's only available for spring dates...which doesn't help us at all since we are hoping to go in Nov.
