AAA does discount rooms. This can be done for a room only through disney or through AAA. If you are wanting a package you can get that exact same discount towards a package....the same amount of the room part of your package with full price for tickets (and Dining if you want it). The discount is only off the room part not off the entire package price.

You can figure out about what your prices should be by gowing to disneyworld.com get a quote for what you want. Then on disneyworld.com check the room rate. Figure the discount per night by multiplying the proper percent then add tax by multiplying by 1.125 (1.135 I think for allstars) multiply that by the number of nights,. Deduct your discount from the package price you got from disneyworld.com. That is about what your aaa package should cost. You can then call aaa to get an exact quote. If they are charging a lot more find out why (maybe there are differences in what they are quoting). If there is no reasoning for it try a different aaa office. You dont have to use a specific one.
