This past May we canceled just hours (the night before our flight out) for a 14 night stay at the A/S Music, so cancellation do occur. We were lucky enough to not have disney charge us the one night deposit because of a family emergency. (The airlines didn't charge us either). When things were better, about a week later, we tried to salvage our trip, so called 2 nights prior to leaving again and were able to get into the a/s Movies at a CM rate for 9 nights. So things do open up. I guess I freed up alot of nights for many people by canceling my original reservation, and in turn I still managed to get into the A/S Mo. at a discounted rate just 48 hours notice.
