I would offer one possibility that I've grown to like:
Wyndham's Owner Priority dates.
At several resorts, during the most in-demand times of year, an owner can:
- Book whatever they want with themselves as the lead guest
- Book as many other units as they want for their guests traveling at the same time*.
- Book up to two reservations per year for unaccompanied guests.
The limit of two is across all restricted resorts/periods.
For most small-scale owners, this is just fine--we are unlikely to rent more than once or twice a year, so this doesn't matter. It can make things a little complicated if you often send your adult children on vacation without going along, but the solution to that is to add them to one of the deeds/contracts. (Wyndham allows differently-titled properties in the same master account; the owners of "the account" are the union of all of the owners on each property.)
It can even work well for folks who rent more often; they just have to choose times/resorts that are not on the restricted list, and plenty of those exist.
When this plan was implemented, availability at some of the toughest-to-book resorts got MUCH better in a hurry. For example, it used to be next to impossible to get summer dates at
Glacier Canyon in the Wisconsin Dells without owning there--and even that required effort. Now it's quite a bit easier.
Also: most of the large-scale Wyndham renters
hate this, and many other rank-and-file owners (though not all of them) seem to think it is just fine. That tells me that it's targeted reasonably well.

*: Last I knew, the dates did not have to line up exactly; as long as there is some overlap it is fine.
