we use our BCV and/or SSR points to book BWV every late april-early may (at exactly 7 months). we have gotten our BW view studio, despite having to WL a few times, every year.
there are more studios than 2BRs, but you still have a good chance if you will take any view. standard and BW view may very well be gone, but a PG view is likely.
remember that you can book a PG 2BR, and waitlist for the other views so you know you at least have a room.
