If you're an AP holder you can log in and then you can view the discounted rates. Right now on Disneyland.com they have the fall rates until Oct 1st and I believe it was 30% off room rates. $450 off package rates. Winter rates probably won't come out until after this current promotion is done.

Forgot to mention that Expedia usually has rates a bit cheaper than Disney's website.
