Do I have this straight? If I book a package with AAA I only get a discount (whatever the discount is at the particular date) on the room portion? Not the whole package price? But isn't the Disney package cheaper than buying the room, the tickets and the dining plan seperately? So what is better?
AAA can either book you a package with the AAA discount on the room portion of the trip
OR they can book you any of the regular Disney discount packages...but on that you're getting the same thing you'd get if you went direct through Disney (no AAA discount on top of it - no matter where you book you cannot "stack" discounts. If you're getting a room discount, you're paying full price for tickets & dining...if you're getting free dining, you're paying full price for room and tickets, and so on.)
There's only 2 reasons to book through AAA. One: no other discount is available, so the puny 10-20% room discount is better than none. OR Second reason - you really want the AAA Diamond parking pass or Belle's Storytime feature (or whoever the current character read is with.) Other than those 2 features, the Magic Your Way package you book with AAA is the same as the Disney MYW package.
Except, when you book directly through Disney, they don't charge any booking fee AND you can call Disney up directly and make any changes you want.
As to what is better, you just have to run the numbers & see what comes out cheapest for your individual situation. By the way, you cannot actually price it all separately and get a better deal, because you cannot buy the dining plan un less you have a package of room & tickets + dining. Either book the package through AAA or book it through Disney, either way, it's got to be a package. The only exceptions are some ticketless packages available for Disney Vacaction Club members (DVC) or Disney Annual Passholders (AP)
Don't get me wrong - we love AAA for discounts at hotel rooms elsewhere, for the security of the road service, etc. But Disney - no way, not in the current climate of great discounts available direct through Disney. Three years ago we loved getting the 15% discount on our Disney room because there was absolutely no other discount going at Disney. But now, no way...Disney's own promos are far better than 15% off the room.
