If you look around, there aren't that many resales available!! I've talked to a couple people who were selling their points, one sold because the wage-earner lost his job, and they owed money on the package... the other sold due to poor health conditions....
Other reasons would be divorce, death, and changing vacation plans, although I think that particular reason doesn't come up too often! I look at the resales that do come up & I see they've borrowed into next year already, they OBVIOUSLY liked the Club, but for some other reason are selling....
I say just buy, you'll be glad you did...
