Remember, the rules apply to the owners and whether people agree or not, each of us has certain rights that go along with it…and one is the ability to rent points without needing DVCs approval to do so.
So, they could certainly try to set limits on third party use when renting but that would then apply to all offers, including points. And I don’t see
DVC do that and getting into a challenge when there are a lot of things they can put in place that defines commercial purpose strider than they do today.
I get confirmed reservations are things people don’t like but I don’t see how offering it that way vs on demand makes it commercial use of a membershp.
And that is the only thing DVC has the right to do.
