I've notice the price spike too and it doesn't make sense. Many of these sellers are asking BCV prices for VWL. BCV is the other small resort but in such high demand that it's difficult to purchase it directly from Disney (there is a long waiting list). So in the case of BCV your choices are: buy resale and get it now or buy from Disney and wait maybe as long as a year. So it's not surprising that BCV resales are as high as they are.
In the case of VWL, it doesn't make sense to me. You can purchase VWL directly from Disney for $92/point. You will get current year points, pay pro-rated dues and not pay any closing costs. I see resale contracts listed for close to that price so with closing costs, you will pay more than if you bought directly from Disney. Some of these contracts have very few or no current year points. So I think it's just sellers looking at BCV prices and thinking that VWL should sell for the same price. If potential buyers are doing their homework, they will realize that those prices are out of line.
