If the AAA agent you called is not returning your calls, please call another agent. You do not need to use the one closest to your house at all. My agent is pretty good in general. She knows Disney.
I am saving close to $400 off a trip to the Polynesian in July (8 nights, 9 days hoppers,
DDP, 5 people) when there are not other discounts available, and last year, we saved over $300 on a similar trip to the Poly. I got quotes from Disney first and then called my AAA agent. Mind you, I did this in January and we're going in July, so it was several months out, but there are significant savings possible.
If you book a room only, you can do that through Disney and get an AAA discount applied, but you cannot get tickets or the DDP that way. If you want tickets and the DDP with that AAA room discount, you need a package, and only an AAA agent can get you the AAA rate.
But AAA rates need to be booked fairly well in advance because there are only a select number of rooms at each resort and of each type available with the AAA discount. Anyone who gets the same price quoted from AAA as they get quoted from Disney is not getting the AAA discount applied to the room portion of the package.
