I am booked at POP for October 7 through 11 (mermaid was booked). We booked with a AAA discount, I think it works about to be about 10 to 15 percent. It appears that Disney’s discounts probably won’t work on the holiday (looks like these are blackout dates). But, I am waiting to see if Disney releases a resorts only for the Fall past September 29th.
I did hear, however, that there are no discounts for the new resort. Good luck!
