I had a reservation last month at BWV that I had to change dates a couple times because of work. When I changed my dates in September, there were no studios for Nov 10-15. I booked an AP rate of 35% off, it was around $285 a night with tax. The preferred points were 15 per night. I did end up getting it on points through stalking the website and grabbing nights as they came open, plus one night came through on waitlist. So be sure to compare all options.
