I know the restaurant board has a cancel thread to let reservations being cancelled hopefully get picked up by fellow Disboarders. Has it ever been considered to have a similar thread on the DVC forum? I know wait list probably picks up most of the cancellations, but given that some people have more luck stalking, a "cancellation" thread might be a good idea.
It really only works for the DVC rooms if there aren't any waitlists set up. I tried once to coordinate with someone for a night I needed but it did not work. Restaurant reservations don't have waitlists so timing can work although even then you might run into someone who happens to be searching at that time so not always.
I wondered if there's a difference between people waitlisting for 1 night vs all the nights that come available. If someone put in the same dates that I'm cancelling and there is no other waitlist for that exact reservation, would it match before partial nights? Might be worth a try which is why I posted.
