I am not able to see how buying, stripping and reselling a contract is hurting the membership, nor do I see why DVD would care.
Renting does not hurt the membership as a whole, either. We forget the DVC does not care WHICH member booked the room. It only cares that the room has been booked.
Posters here are arguing about "fair" - how to allocate scarce resources. We will never agree on that.
I agree that any notion of "fairness" is rather specious. No matter how many changes DVC makes to the program, we will never reach a point where everyone is satisfied.
Specific to this thread, I think the idea is that if any hard-to-obtain accommodations are going to spec renters, it's a bad thing. Hypothetically if there are 10 BCV studios available for December 2nd and 50 people hoping to book right at 11 months, any of those 10 rooms falling into the hands of a renter is bad. Of course, most of these arguments focus on those truly hard-to-get accommodations. Even if we remove renters from the equation, there are still a couple dozen people who won't get their desired room. But in the abstract, I think most members would agree they'd rather see all 10 rooms going to run-of-the-mill DVC families with plans to stay there rather than 8 rooms to those families and 2 sitting on a website as spec rentals.
10+ years ago, the DIS seemed to be the de facto place to go to rent points. And the board had a rules against renting most confirmed reservations. I always assumed this was to discourage spec rentals, and I thought it was a rather noble clause which helped to discourage the practice.
Does DVC care about this activity? So far, there isn't much evidence that they do. They did bother to write these "personal use only" clauses into the POS and have communicated anti-rental messages a variety of times. I'm not sure that we've ever seen any explicit action though.
Every owner has a legal right to use their points. But some of the practices are damaging to the program as a whole. For example, there are villas being booked as spec rentals and held until exactly 31 days out. If not rented, the reservation is cancelled just before the holding rules come into play and the points are banked or rolled to a new set of dates. Even points that fall subject to the Holding rules can be rolled to new dates if availability is aggressively monitored inside of that 60 day window. Rooms cancelled on a few weeks' notice have far less chance of being rebooked with points. It's lost capacity. Do that a couple thousand times per year and it adds up.
Cracking down on certain practices would unquestionably help availability. Though probably not to the degree that some want to believe.
I have no quarrel with someone who says "I've got 200 points to rent (or 500 points, or 2000 points) at $$$" and offers to check resorts & dates. I don't care how many points they own or what method they use for renting (DIS, broker, Facebook, etc.) But when people proactively tie-up availability with no customer lined up, yeah, I think it hurts everyone. Especially when failed spec reservations lead to short term cancellations and rooms that ultimately sit empty.
