For me, that still argues against renting. Every time I look, ROI on rentals for resale points is usually at best equal to the long-term post-tax rate of return for a diversified low-fee stock index fund. Usually it's a little less. It doesn't really matter which resort. Yes, prime resorts get more annual revenue, but their cost basis is higher making it a wash.
(If you think about it, this should not be surprising. The invisible hand strikes again!)
But, renting is more work vs. the set-and-forget of an index fund. What's more, the diversified nature of the fund spreads risk, vs. DVC rentals which focus risk---and that risk is correlated with your own desire to travel. So, exactly when you might want to travel less often due to outside factors, and put more of your points up for rental, everyone else wants to travel less too.
