Did you ever go look at the site from the original post? I don't know how anyone could look at that and trust that DVC was actually looking into and enforcing a limit of 20. And it's all over the place, it's not only one rental site.
I'm certainly not talking about some draconian slippery slope of clamping down on DVC. Whether or not it's doing anything to your personal rental habits, there is absolutely a market out there that has enough profit for people to write bots just to book rooms to be sure they are getting the only ones to make more money from them. There are companies listing hundreds if not thousands of reservations. Maybe there are 1-3 nights at a time, but it's staring us in the face that someone is either getting an exemption from the policy or is going to extreme measures to fund loopholes to work around the policy. Do you honestly believe Disney implemented a limit of 20 so that companies would go buy 100 different memberships to rent 20 from each? And that this was how they meant for DVC "personal use" to be interpreted? Questioning if it's real is ignorant at best, the issue is how could it be dealt with reasonably because it should be.
DVC used the word "membership" in 2007 when setting the rules. Maybe there was a legal reason that rules have to be applied to individual memberships, regardless of whether an owner has multiple ones? I have no idea but it is something that just popped into my head.
I own three memberships and can't use them together, and am treated as though I am three different owners. The only way I can is if I transfer points from one to the next. I can't merge my reservations between my memberships either. So, when I book, I have to choose which membership I want to work within. Maybe its the same with enforcing rules in our contracts? Think about it, there must be a reason why owners who own multiple UYs must be given different memberships, right?
If, we assume, that all of those rentals are on memberships that have the same, or a combination of the same owners, but there are enough memberships holding them, then isn't it possible that DVC has to apply the rules to each on individually since legally, they are individual memberships?
Maybe that is why, assuming DVC is using the 20 reservation rule still, and they are monitoring, there is nothing they can do because they can't enforce rules against an owner, only the membership which holds the contracts?
Here is what I am thinking. I decide to use my Dec UY membership, which is owned by my DH and myself and I rent 15 reservations. I then use my Aug UY membership to make another 15 reservations, but this membership has my adult children as additional owners (on the contracts).
Each of those memberships, if we use the 20 reservation rule, on their own, would still be considered being used for personal use. Now, because DH and I are on both, you can say "we" have 30 rental reservations, as individuals, but my adult children, as owners, only have 15. So, can DVC really penalize them, when legally, what they own is not being used for commercial purposes?
I just have to wonder if there isn't something we don't know about what legally DVC can do to owners whose memberships, individually, are not being used for commercial purposes, but if you lumped them together under one membership, they would be.
And, maybe, just maybe, this is why the whole concept of owning lots of membersihps and staying below the limits is allowed to happen.
