I also will be in WDW in early Nov and have been calling to try to switch to a different resort. FOr the time we'll be there I've been informed by CRO on almost every call that they are very booked for that week (11/1-11/9).
HOWEVER back in 2001 when we stayed at the Poly I initially could only get an AP rate for 1/2 the nights were were there. I was told over and over that I would "never" get the AP rate for all the nights because the resort was sold out for 1 of the weekeds we were staying.
After many, MANY, MANY calls I finally got all the dates I wanted at the AP rate, so being persistant can pay off! I always had better luck calling right when they opened, so maybe you can try that angle if it's an option for you.
Good luck!
