We booked through AAA only for the fast pass perk...everything else included in the package is about the same as what I could get booking through Disney on my own....and my agent did tell me that there is a $4 dollar difference in the AAA quotes, but I can deal with that....So I guess unless you want the Multi-pass, there is no difference because on the buy 3 get the 4th night free offer, they charge rack rate for the 3 nights anyways. Still turned out to be cheaper than any other discount.
