Just a heads-up...the actual room discount can be as little as 5%...and if you're booking a package through AAA you will not be able to get discounted tickets on the package (the same one-discount-per-booking applies through AAA too.) You can book any of the discounts through AAA (even the
free dining) but when you book one of Disney's discount through AAA that's all you get (they won't give you both free dining AND the AAA room discount, for example.)
we used to book through our AAA office, but quit a couple of years ago when they started charging a booking fee ($10 at time of booking and $10 each time you make a change...these are AAA fees, not Disney change-fees.) So when booking a package deal, like a free-dining discount package, it actually cost $10 more to book through AAA than it would have cost to book myself. Most of the "benefits" in the AAA packet are exactly the same you get from Disney for the Magic Your Way package. The special parking is worthless at Magic Kingdom parking, so-so at the other parks since depends on what end of the row you get. If you're lucky it can be very close, but just as likely to have you on a long hike (and tram service does not stop at AAA diamond parking at some parks...so you can end up with a longer walk sometimes.)
AND to top it off...I had to tell the "Disney Specialist" what discounts were available...and your Disney packet (mickey mail) goes to the AAA office , and then they are supposed to mail it on to you. Last straw for us was the trip we booked, got to be about a week before the trip and we had not yet received our packet...called the AAA agent and she says "you're supposed to come in and get it" First of all, no one called or emailed to tell us to come get it, and second of all, it was a 90 minute round-trip drive to get to their office so we really would have preferred they just mail it out, but by then it was too late, we were leaving in a couple of days!
