We also cancelled our BCV reservations and we were able to get a 1BR MK View for 8/20 to 8/23!
Got through at 9am and was on hold for approx. 15 minutes. The reservation took another 15 minutes to make. I made sure I had my "Vacation Details" on my computer screen and the BLT ressies were there as soon as she locked in the room!
We got right in at 9:00, had no hold time so we were one of the first in the queue. Got our nights at THV for July 18-20 to back up to our AKV reservation we already had.
