whether we think its its a problem is sort of irrelevant
Maybe not entirely.
I've been following the rental saga with Wyndham almost from the day I first bought points--and that's pushing 15 years ago now. Most of the steps they took were targeted to extreme cases, much in the same way as the 20 reservation limit, the one-transfer rule, or the limit on Associate Members did.
For example, they limited the number of reservations at a single resort that could be held by one owner to 10 or 10% of the resort, whichever was smaller. This rule was put in place largely due to a specific owner who was booking dozens and dozens of rooms each holiday weekend at the Wisconsin Dells resort with an indoor waterpark. A change in how credit borrowing worked was mostly in response to a single owner who had made a nice business out of buy-strip-flip. They put (large) limits on free guest certificates for high-status owners that used to have an unlimited number, targeting a handful of mega-renters.
But, most of those changes were around the edges, and day-to-day owners never noticed.
That all changed post-pandemic when all of a sudden Wyndham got VERY VERY SERIOUS about curbing renting: A couple of big policy changes: owner priority periods that limited guests at more popular resorts during peak times, plus no longer offering VIP benefits on reservations booked with resale points. That was combined with a very aggressive campaign of sending cease-and-desist letters to owners they thought were renting "commercially," along with following up with real teeth for those who neither ceased nor desisted. Most of the larger Wyndham renters on TUG either cut way way back on what they were doing, or out of the business entirely and liquidated holdings.
Reading between the lines and watching the tea leaves at the time, I'm convinced a big reason why that happened was a sharp increase in owners angry that they couldn't get the reservations they wanted. How much of that was due to renting vs. post-panedemic revenge travel among owners with a year or two worth of banked unused points is not clear. But, there was a lot of vocal, negative attention focused on renters. If that vocal attention made it to the sales floor in a way that reduced conversion rates, then that's an easy explanation for how seriously Wyndham took this in a short period of time when they mostly never cared except for the egregious cases.
I can imagine the same thing happening to DVC as the rental ecosystem continues moving away from a price-per-point model to a confirmed-reservation model. And, that evolution is inevitable, because you can get better margins on specific room categories than you can with generic points. Of course, it just so happens that those rooms are all studios, and that
also happens to be the room category that sold out first even before this change.
If owners complain more loudly about availability, and blame the spec renters for it in a way that shows up on the sales metrics, then that will get DVD's attention, and they will get to work.
