I called a couple of weeks ago to change a December booking from 12/18-12/22 to 12/16-12/19. Both bookings were for 1 BDR at BWV, Boradwalk view. There was no problem changing. As a matter of fact, there were several variations I asked about and they were all available. This call was before 9/11. I can't help but think it will be less booked now - odds are good some people are cancelling.
