Regardless, my comment was in response to this:
Disney prefers to have 2 rooms filled over just a single one. However that can be done, Disney wants as many rooms filled with as many human beings spending money on Disney property as possible. The question wasn’t whether that was viable, or even likely, or what that potential renter might go or do otherwise, but what Disney would prefer. My point remains: if presented with two options, one being me renting my points to someone and them staying in that room, versus me using my points to stay in that room and the potential renter paying cash for a second room, Disney will prefer the latter.
