I've done AAA three times now, so I sort of know the ropes.
See
www.mousesavers.com for AAA discount rates which vary depending on the resort class and season of travel.
The AAA discount comes off the
room portion of a package if you book a package. To book a package with the AAA discount, you must use an AAA agent. We're saving $400 off the price that Disney's CRO quoted us for the eight nights at the Poly. Generally, the more expensive the room, the more you'll save because it's a percentage off.
The AAA discount cannot be combined with any other discounts; therefore, if you're looking for
free dining or one of those elusive codes people get, you cannot double dip so to speak and get that deal on top of AAA. It's only one per customer.
Some AAA agents are better than others, and some are misinformed.
If you want a room only and not a package, you can book that directly through Disney and get an AAA discount. However, you cannot get the
DDP if you go this way because the DDP only comes with a package.
If you book a package with AAA, you do get a few perks including preferred parking at the parks, a discount for shopping in DTD, and the AAA Storytime at MK.
