The advantage of adding PVB2 to the same association would be that otherwise the resale price for PVB1 would plummet, creating problems with ROFR and sales. Would you buy a resort with only studios when there is a newer Tower next door with a balanced number of units in different sizes?
While that could boots PVB2 sales, if PVB1 price plummets, then it will be competition for PVB2. Maybe you'd prefer PVB2, but what if PVB1 is half price resale?
DVD, which builds the resorts and collects the funds from initial direct sales, is unconcerned with resale values. They literally don't make a dime off resales. Their goal is to sell the points for as much as they can, as fast as they can, and move on to their next project.
If it's a new association or part of PVB, I'm not convinced that the number of existing
DVC owners buying there will actually change. Some, like me, wanted the location of the tower in the first place. If it's a new resort with every size villa, I'm in (and will likely sell my BLT, which has greatly grown in value, to get it). On the other hand, I know people who are PVB owners who have "grown out" of studios as their children get larger, and want to stay at PVB in 1br/2br units. They would add on to bring their point total up enough to stay in a 1br/2br every year if it was part of PVB, because they need the large villa. They aren't likely to sell PVB (at a distressed price) to trade up to the Tower, so they'll play the 7 month game.
For new members, I also don't see a difference between a new association or part of PVB EXCEPT FOR resale restrictions. That may play a small factor. I think that being part of PVB (unrestricted) would ease the sales a bit, since the guides don't need to talk about it, or potentially scare buyers away because of it.
There's also an economic aspect to this. Being part of PVB would allow them to resell the tower faster than the standard 50 years. PVB will be almost 10 years old when the Tower opens. That gives them only 40 years before DVD's next payday.
When DVC converted more of Wilderness Lodge to create CCV, they perceived that BRV's
point charts would hamper sales of CCV if CCV had a higher point requirement. So, CCV has a fairly low
point chart as a result. This is not the case with PVB's point chart. While it's less than RIV, it's still much higher than BLT and AKV, on a par with GFV.
I'm of the opinion that the Tower will probably open as part of PVB, and will feature fewer studios than the standard mix for that reason.
