The AAA site does not give pricing information. Mousesavers has some information about what you will save by using AAA on a "room only" reservation.
I just booked a package through AAA (rooms, dining, tix) and saved about 6% of the cost through WDTC.
You must get AAA package pricing through an AAA TA; you can get room only discounts through AAA or Disney CRO/WDTC.
Hope this helps.
