I've brought this up here in the past on these boards before, but what do we think about a guest certificate system? Absent any further or more stringent efforts from DVC to curb commercial renters, I would think an aggressively priced guest certificate system--say, 2 free guest certificates per UY for when the member or associates are not on the reservation, then priced at $100 and progressively increasing for each additional guest certificate--could discourage commercial renting.
If the current rules/structures make it difficult to curb commercial renting, then let the market decide. Once the 4th+ guest certificate comes in at say $400, it will be difficult for commercial owners to simply pass those costs along to the renter. The delta between rack rates and
DVC rentals are getting tighter as it is with AP/locals/
disney+/[insert promo] discounts, so something like this could effectively kill commercial renting without resorting to potentially endless legal battles. And I wouldn't mind if such guest certificate fees be treated similar to breakage income as a revenue component on the dues statement (but who are we kidding, we know DVC will gladly pocket that extra money).
I'm sure that implementing such a system would require some rules changes, but other timeshare systems implement guest certificate systems and seem to enforce "no rentals" policies better than DVC. I know there are detractors to such a system because they often gift out stays to friends and family, but perhaps if you're giving out more than two reservations a year, maybe consider adding them as associate members.
