You are having trouble with the Villas because that is during the Food & Wine Fest (ends Nov 13th). Most of the Villas are owned by DVC owners. Most owners reserved space at the 11 month window to be sure they could walk into the Festival easily. BCV is also probably sold out , and I had read somewhere that even Swan/Dolphin had done away with all discounts for that period because the rooms would sell easily at rack rate.
There are very few Villas that can be gotten through Disney directly. They have a reserve of about 5% of them plus they would have any that DVC owners had "traded" in to maybe take a cruise or something. If there are any cancellations, they will probably be snapped up by folks on the waitlist, which is probably quite long as November is only 4 months out.
The only solution I can think of is to watch the Rent/trade Board as it gets closer. Sometimes a DVC owner has some type of crisis and has to cancel a reservation they already made. If the owner is unable for some reason to "bank" the points, they will probably try and rent the reservation out. It's a long shot, but it could happen. I know, because last year DH had surgery and we had to cancel our trip at that time. Couldn't bank the points, so we ended up renting the reservation out.
Sorry to be the bearer of bad tidings. If you can get a DVC reservation ANYWHERE onsite I would grab it, as they eventually will all go.
