Fine, I'll address the other issues as well.
SSR is not the only factor that has changed. Interest rates on loans, travel costs and the general economy has changed during the last two years, as well. People don't have as much discretionary spending $$ as they did. It costs more to just drive to and from work, to buy groceries, etc. Almost every cost of living has increased because of increased energy costs, but in most cases wages have not increased by te same percentages. It is just as plausible that those factors have increased the desire of some folks to reserve and rent the ressies during the 11 month window.
If a person calls and reserves 50 units on day one of the 11 month window, it does take that many units out of the pool available, just the same as if 50 individuals called to book the same thing. But using your own suggestion that "owners" should be more entitiled than non-owners, then you should also be opposed to that type of commercial renting, as the people who rent those pre-made ressies are NON members, not owners at that resort. In otherwords, an owner is giving non-owners unfair advantage over other owners at that resort.
