Take a look at
www.mousesavers.com
They often have discount codes for the resorts, it's not too late!
You might be surprized how affordable AKL can be, call WDW reservations and even if you don't have a code, tell them you are curious about how much it would cost to switch resorts. When they give you a price, ask if there are any other discounts available. Can't hurt to try!
Have a great time!
