If you are interested in a AAA room only reservation, you can make a room only reservation now, by calling disney. They will charge you a one night deposit based on the peak 2008 rate for your resort. Then when the AAA rates are released you can call and apply the discount to your reservation, assuming a discount is available. If you are interested in a AAA package, since this needs to go through AAA, there is probably no advantage to making the room only reservation now.
