If Disney didn’t see a benefit in maintaining Riviera resale restrictions, they wouldn’t be there. There’s also zero evidence that Disney doesn’t like having a studio only resort. The lack of ROFR on Poly, as I’m sure you know, can also indicate that Poly2 will be in a separate association.
I think it would have been a reach to see VGF2, a quickly converted older hotel wing with zero amenities of its own, formed with a separate association, so I don’t think its status has any bearing on this discussion. But VDH, Poly2, and Riviera exist on an entirely different level, all being huge new builds costing hundreds of millions of dollars. These and other resorts down the line are the reason for the restrictions. And they work! I bought a bunch of direct VGF points specifically to book Riviera at 7 months, and potentially other yet to be built resorts in the future.
If VDH has the restrictions, so will Poly2. It would otherwise undermine DVD’s long term goal of competing more effectively with resale, and confuse buyers.
