My answer probably won't be what you want to hear. We've been very unlucky with the BCV wait list. Several times it never came thru. The one time it did come thru, we'd gone on the waitlist at 7 months (minus 3 hours) and it came thru exactly 30 days out. Granted, this was during the food and wine festival, but I was especially surprised because just a few days before the 7 month window opened, they still had availability for what we wanted there. I was surprised that either we were so far down the wait list in that few hours, or that so few people cancelled their reservations.
Just spoke with ms yesteeday about bw waitlist...she told me it is hard due to limited availability. The best bets are always ssr and okw. I have also had 5 waitlists come through for akv. Good luck
