VGC is a completely different animal than any other
DVC resort. It is small and exclusive.
Also, it is the easiest resort to rent or transfer points and so an owners can easily wait out soft markets with rental income.
With that said, look at the average DVC sale price reports (they will show you what things sold for, not listed for) at some of the larger brokerage sites to get an idea of where the market currently is.
It seems that currently there is seller resistance at around $240 with the occasional blip where a broker drops the price and it gets snapped up quickly.
