When I booked our stay for late June (7 month window), they also had studios at VDH that were available to book. I wanted a 1BR though and was able to get it at VGC. Studios at VGC for our dates were long goner though.
For those not aware, the resorts do have different "seasons" for the
points charts with substantial differences. For example, VDH has one (relatively pricy) "season from June 1 to August 15, and gets about 25% less expensive from mid-August to mid-September. On the other hand, VGC has a cheaper points chart from mid-April through late June and gets about 30% pricier(!) from June 29 until after Labor Day.
So those wanting to travel in late August or Labor day pay a huge premium at VGC relative to VDH.
See for example below rates for late August through Labor Day:
