Absolutely!
I’ve given it more thought than I should lol.
The best I’ve come up with is adding a check box where
DVC point reservations are added to
MDE. Put it right on the page with the other ‘Agree’ check box that exists. “If this is a point rental you must check this box to confirm you understand a rental contract is required.”
It’s very low-key. Not threatening. Pleasant, no cause for alarm type of thing.
It wouldn’t bother owners doing the occasional rental. They’re fine. Their renters are fine.
The only issue will be to commercial renters because they’re caught between having to coach their rentee against checking off it’s a rental with a proper contract, or DVC having record of all their rentals. But if I’m renting from a stranger, do I really want to open myself to issues by not complying with the checkbox. Is it worth it? I’d rather just go find a rental where that owner doesn’t care if I check the box… and that would be somebody who is not crossing the line into renting as a business, for profit, commercial, etc. And if I were crossing those lines, I might think twice about letting all those rental checkboxes happen if I’m used to never paying taxes on them, among other things.
Might be a solution. I have no doubt the heavy hitters’ activity negatively affects casual owners, and cash rooms too. Maybe DVC’s just waiting for the right opportunity

Get their ducks in a row now - making sure to maximize ways it could benefit them. Have that ready to go. Also aim for the best timing - when this kind of transition will be easiest for them to get their preferred results.
