That's the kind of thing that is REALLY going to scare off a lot of owners from using David's in the future. I have not used David's to rent out my points, but I was keeping his service in my back pocket in case I ever had some points that I wouldn't be able to use for some reason...But now, I don't think I would be using David's...
I kind-of-get the argument that the owner "cancelled the reservation via Disney doing it and Disney is acting as the owner's agent" kind of thing...and David's wanting their money back or refusing to pay the 30% based on the reservation being actually cancelled.
But for David's to make that argument as a basis for refusing to pay the owner their 30% and then turn around to the RENTERS and make almost the exact OPPOSITE argument while refusing to refund the renter is certainly contradictory. David's is trying to have his cake, and eat it too. Going to the renters and, essentially, saying the owner didn't cancel your reservation...Disney did...so you aren't due a refund...but out of the graciousness of our hearts, we will let you rebook at some point in the future (* - some restrictions apply). He is arguing both sides of the coin to the different parties to the transaction and making the argument to each party that is most beneficial to David's.
If I were an owner, I would be okay if David's didn't pay me the 30%. I understand a lot of owners don't agree with this, but I would be okay with it. It's a situation that is literally hitting EVERYONE and I think it's fair for that pain to be felt equally. If he didn't pay me the remaining 30%, I would consider the points mine, at that point, to use as I see fit...him paying me his original 70% is actually pretty darned close to 50% of the total amount of money he collected from the renter.
I would then attempt to work with David's to reasonably re-rent the points as best I could within the restrictions that are on those SPECIFIC points (use years, expiration, banking, borrowing, etc.) If I re-rented, I would want the remaining 30% right away...not at check in... and I would consider that the points would belong to David's for him to use for the benefit of the renters...he could cancel, re-rent to more renters, etc...I wouldn't care...again within the usage limitations of those specific points.
If he couldn't find a renter within a reasonable amount of time before points expire or I couldn't bank them, etc...then I would just book a reservation for myself, upgrade one of my own reservations, RCI deposit, or gift them to a friend/family member and walk away.
Since Disney extended points expiration on reservations that were cancelled due to COVID, then it's a lot easier to work with David's on re-renting or to better plan for using the points myself.
If David's is ALSO refusing to pay owners their 30% for that weird period around where the parks were closed but resorts were open, then that is COMPLETE BS...IF that's true, I would DEFINITELY not rent my points through David's ever again. There is literally no argument for not paying on that reservation. If David's wants to give the renters in those cases his voucher, then that is HIS prerogative, but those points would definitely be used with no recourse from
DVC...he absolutely should pay those out.
