I think you are jumping to a lot of conclusions here when you say they are prohibiting rentals.
The only thing they did is make it less convenient to change a guest's name. We should be upset when a management company works to inconvenience owners, and I will be happy to cite it as an excuse not to buy more, but from that to a class action is a big jump. That new policy can be justified by saying that they want pre-arrivals to get requests in a timely fashion or perhaps marketing wants the guests' information.
I personally did not get the email. But have you been inconvenienced in any way from the new policy? Have they told you directly that you cannot rent your weeks? There is one tug member who claims in multiple forums he's been highly inconvenienced. That person joined tug in 2020 but his signature line claims he's been a member since 2000. That same person has 14 posts on tug total, all of them on this topic since late May. And that same person claims that
southern states promote daily shootings with AR15s (although the post may have been edited since) Until there is more real evidence that rentals are actually being restricted, I think we can just wait and see what happens.
To the extent they limit rentals of home resort weeks, that is a problem and highly questionable. Some owners may use their weeks in a given year and rent them all the following year if they take a cruise, or overseas trip. Some may use weeks in destination A and rent destination B, and vice versa next year. Some may have bought weeks because they thought they are retiring, and went back to work after the market dropped 30%. Either way, people can rent for a variety of reasons and weeks home resort usage should be almost untouchable, in my view. To the extent they limit rentals of point reservations (from elected points) they may have more justification to limit that, although it will also starve abound of inventory in the long run, since people won't elect points, so it's a double-edged sword.
I have a July rental myself (week home resort) that I'm still trying to rent, and it may rent within the 30-day window. If the new policy will limit my ability to add a renter in a timely fashion, I'll be more pissed off. Let's just see how it plays out...
