Last December first week they had a pretty steep discount available at the last minute through Travelocity (and probably also through CRO). I wouldn't count on it again, I think it was a result of alot of cancellations after 9/11.
I was staying on DVC points and just for the fun of it checked availability on travelocity about a week before we went. If it would have been sooner, I would have cancelled my Saturday night on points and paid cash, but DVC has rules about cancellations less than 30 days (holding account...). Saturday nights are high points through DVC.
