I saw the room VGF is a deluxe studio so that is in the original villa building with the split bathroom setup and true kitchenette.
Is the PVB studio a longhouse studio or tower studio? I would probably try the studio if it's in tower since it's brand new and you can experience that new building. If not, I would prefer all the villa accommodations at VGF to PVB longhouse studios. They're too dark for me and a much further trek to MK. On the other hand you can walk to TTC and jump on the Epcot monorail if you want from PVB longhouses since they are on that side of the resort.
