Holiday season is that one week around Christmas. If you look on Disney's site, or any others that break down the season you will see value, regular, peak and holiday. So there just aren't any discounts during that holiday season.

With AAA you pay just like you would any other package. If you are doing room only, then you just pay the one night deposit. If you are doing a package, you have to book that through your AAA agent and I am not sure how they have it set up because I only use AAA to get the room only discounts.
