MId-Sept through mid-January is the busiest time for DVC. You need an owner with the home resort advantage and not wait until seven months out. If you are looking at the holiday, that needs to be booked right at 11 months out. The problem with the brokers is that they might not have the owner with the points you need at 11 months out. The newer resorts are going to be much harder to book since the owners who bought their points at the new resort want to use them at the new resort and not rent them out. I take it you are booking at two bedroom villa and not a studio that sleeps five. Unless you aren't going and just need a villa for four persons. Every BWV two bedroom is a lockoff villa, meaning is it composed of a studio and a one bedroom. So when studios are booked, there are no two bedroom villas.
