Good luck to you! As I mentioned on another thread, I was on the waitlist at David’s for 10 weeks before I finally got my reservation for a 2BR at Beach Club filled.
One thing that should make you feel better is that David’s recommends that you book the Polynesian only 7 months or more in advance. In other words, it’s not one of the resorts they recommend booking 11 months in advance, so it’s unlikely to be fully booked prior to the 7-month mark. Fingers crossed for you.
