I agree. I really think that once there are sufficient Resale Owners (and it will probably take less than 10%), then Riviera will be a special case, and substantially different compared to other resorts in the past.
Resale owners will KNOW that the only way to use their points will be to Reserve something during the 7 to 11 month window. Because if they don't, then they won't be able to use them anywhere.
NO OTHER RESORT (so far) HAS THIS PROBLEM.
This means that most Resale owners will either be booking early, OR ELSE RENTING THEIR POINTS OUT, so that they get some benefit from them. RIVIERA points will become some of the most Rented points of any DVC resort.
Since there will be the extra fear that they might not be able to use them, and the fear that they also might not be able to rent them out UNLESS THEY RESERVE POPULAR DATES, the Resale Owners at Riviera will be very aggressive at both Renting Early and WALKING their points. This will put extra stress on other, DIRECT OWNERS, who will have to follow suit, in order to compete and GET POPULAR ROOMS on Popular Dates. IT WILL BE LIKE AN ARMS RACE. So Direct Riviera Owners will also be booking earlier,on an average, and Walking more, compared to owners at other resorts.
Lastly, you could say, "But the Direct Owners can still use their points at 7 months at other Resorts." This is true, BUT IT IS ALSO TRUE, AS WE HAVE SEEN AND ARE SEEING, THAT IT IS GETTING HARDER AND HARDER TO GET GOOD RESERVATIONS AT OTHER RESORTS AT 7 MONTHS.
So, my conclusion is, the Disney Restrictions on Riviera Resale WILL degrade the experience for ALL Riviera Owners, whether Direct or Resale. And the extra pressure will induce MORE Direct Owners to sell, in order to get out of the Rat Race, and this will lead to even more Resale Owners, and on and on.
