In the end it technically is, but I think the issue is that they aren't necessarily "cancelling" yet and it's more likely they are calling to find out their options. Most probably don't know the owners are getting this information. I have a feeling that for some renters if they knew that the owners could officially cancel their reservation and somehow still get the points for future use they'd be pretty upset. Owners expecting that (and full payment or even 70% for that matter) is as questionable as renters expecting a full refund without understanding the nuances of renting/
DVC point system. It's just another tough situation where people on both sides have valid arguments, but in order for logic to prevail it would take the renter being completely understanding and getting no refund (or compensation) while also knowing their owner got all of their money (minus David's fee) and is going to possibly get a vacation on the same points meant for them. Some might be okay with that (given there are no other options), but other would probably balk at the idea.
I only know that in the other thread that the OP posted the correspondence between themself and David's. They posted all of the responses which included scenarios about closing again etc. David's said that they would get the 30% regardless of re-rental or not should the resort be open and if the resort closed again they would lose the 30% regardless of re-rental or not. I doubt they are telling different people different things about this particular situation. If I had to bet it probably has more to do with posters not clarifying what they mean by "re-rent" and what the circumstances are. They are definitely handling closure reservations differently than reservations now that the resorts are open again, but maybe I missed a post in this incredibly long thread...lol
