Heck, I'm not sure I'd call someone "slimy" for renting. I've been guilty as charged. When I broke my leg before a trip 2 years ago, I was really glad we could rent the ressie out and at least recoup something.
If I'd known we could rent DVC points on our first trip to BWV, I'd have been grateful. We paid rack rate for a week as I didn't know any better (sheesh!!).
I may have to rent again as we arranged a reservation for family in April, they backed out. I arranged and re arranged points to use them (i had borrowed points to get what they needed). Even took an extra trip. (It hurt, but somebody had to do it). Now it looks like family is backing out another trip. Fairly sure I'm going to have to offer a rental, or just kiss the points goodbye.
That being said, it does look like at least a couple of people on the boards rent out as an ongoing concern. I've not wanted to judge them, but it does concern me that Disney may get their back up about it, ban the practice altogether, and ruin it for those of us that need to occasionally rent because of circumstance.
