I suspect the PVB studios will have two booking/view categories, if not three. The top floor of the Moorea Longhouse on its north side will offer views of the Seven Seas Lagoon and the Magic Kingdom, so its possible that those studios will command a higher point premium. The Tokelau Longhouse, the south side of Moorea, and the northwest facing side of the Pago Pago Longhouse could fall into a "pool/garden" view category, which should be cheaper than Moorea's Lagoon view studios. The studios on Pago Pago's southeast side face a parking lot, so its possible that those studios will fall into a 'standard' view category and end up being the cheapest studios in the group.
PVB may play out like Aulani or BLT. Aulani is a large resort with 246 studios. However, only 18 of the 246 studios are in the Standard View booking category. At BLT, the Lake View studios -- the largest booking category at BLT -- are almost always available at the opening of the non-Home Resort window. But that is not the case for the less plentiful Theme Park and Standard View categories. If a member hopes to book a Standard View studio for more than the odd day or two, then they need the Home Resort advantage.
Pago Pago is the smallest of the three longhouses being converted to
DVC. Thus, the number of Standard View studios will probably be relatively small. There could be real competition for these studios, especially if they are discounted significantly compared to the Pool/Garden or Lagoon booking categories.
Depending on what you want and what you are willing to settle for in a studio, there could be an argument in favor of buying at PVB in order to get the Home Resort advantage.
