I still don't think it tells us much.... it could be argued either way....
If different associations then they'll want to sell Poly2 and don't need a lot of Poly1 points to offer people...
If it is the same association, then they'll still just want to sell Poly2 since the points will work at both resorts... it won't matter whether they sell you Poly1 or Poly2 since the points work the same at both. They still wouldn't need Poly1 points.
I agree as someone said above, the incentives on Riviera are interesting and I wonder if they are trying to figure out if a "good" price helps people over look resale restrictions. I also still question how important resale restrictions are to the majority of buyers.
