One thing you can do, which is what I did yesterday, is call AAA. Even without being a member they will transfer you over to phone operators who specifically deal with Disney AAA packages. They'll quote you their price versus what you got directly from whatever hotel(s) you are planning to stay with. I had a difference of $240 savings on AKL, and my ressies for HRH are actually better than the AAA rate. So I signed up for it to get the Disney hotel savings. Then, called Disney back to cancel the main reservation, and they matched it instead - which was fine too (you still need your AAA card if Disney discounts it, they just process it directly I guess).
And right now they are offering two adult membership for the cost of one if you select automatic renewal. They still send you a renewal notice so you can easily pick up the phone and cancel before they do a renewal, and saves you more money now.
I've never done AAA, but looks like it'll definitely benefit me with this trip this year! Good lucK!
