We just recently bought resale, and the biggest factor we bought this "timeshare" is because we knew there was a fluid resale market and that
DVC contracts have held their value, if not gone up. We probably wouldn't have bought resale or direct otherwise. If Disney kills off the secondary market, they would be limiting their customer base, I think. With a family of 5 a 1 bedroom sounds a lot nicer than cramming into a single hotel room, but if DVC wasn't going to save us money, we would have limited our trips to Disney and gone some where cheaper (not a value resort at Disney).
