The best thing to do to figure out what resort is best for you is to look at the DVCPOINT CHART link at the top right of this page. There you can figure out how many points you will need for your desired dates at each resort. Then figure around $9 to $10 per point and this will yield an estimated budget for you. For those dates, my guess is the best chance in availability is OKW or SSR, with the least likely BCV or BWV, but I could be wrong.
I have 24 points at $9 per point available for SSR only.
