I'm not sure where you think I am wrong because you basically agreed with me.
Where I think everyone gets a little 'wrapped around the axle' here is conflating a
DVC contract with the person who owns the contract. If you treat a DVC contract as a 'block' for instance, then you can see where the blocks fit, how big the blocks are and what characteristics the blocks have. Thus, the main problem is Disney selling small contracts, ie. small blocks. These small blocks may be just the size of a studio reservation for 3 days. So you can see then that it takes many more of these blocks to fill up the 'bucket' of a studio room at (pick your resort). If Disney had a minimum purchase of 500 points, we would not be having this conversation. There would be far fewer contracts competing for a room. Conversely, it is in the resort's best interest to be as full as possible for as long as possible. That's how they make money. So Disney tries to manage that tension by setting a minimum purchase level.
What we are discussing here is what is the percentage of blocks being labeled as 'unable to be traded' vs ''able to be traded'. At the extreme left end, the percentage is 100%. That is, every contract has been labeled 'unable'. At that point, what will all the points in all the contracts be able to acquire? All the contracts will acquire all the rooms available to book. This does NOT mean that an individual owner will be able to get their preferred room. If all the contracts were small blocks, not everyone will be able to get what they desire. At the extreme right end, there are no blocks labeled 'unable'. THERE MAY STILL BE OWNERS UNABLE to BOOK THEIR PREFERRED STAY because their block size is not big enough (i.e. move up in room cost). This problem means that Disney has erred in managing the tension for booking that resort.
Now what we are discussing is the middle somewhere. I think what
@DougEMG pointed out is why I believe the price of a resale point at Riviera will drop to at least SSR level and probably very much lower as this reality sets in. I also believe that there will be few resale contracts available, relatively speaking, which will help buoy the price of a resale Riviera (or Reflections for that matter) point. I believe the percentage of blocks being labeled 'unable' will be low, probably no more than 20%. It will also be interesting to see how long it takes Riviera to sell out.
