MVC needs Vistana owners to enroll their weeks in the DC if they want to integrate the systems. It especially needs weeks in the locations where MVC has no presence or not a strong one: WSJ, Kierland, Princeville, etc. The issue is how to incentivize the owners of those weeks to enroll and ultimately, to relinquish their weeks for points.
One must start with the realization that not all 148100 or 81000 StarOption properties were created equal (which has nothing to do with whether the properties are mandatory or voluntary). Some properties are just better or just more popular -- and the number of DC points that will be required to reserve them will reflect that. For example, a one bedroom platinum plus Kierland unit (81000 SO's) rents for about $2,350; a two bedroom at SVV Bella (also 81000 SO's) rents for less. There is no internal reason for these two properties to remain equivalent in DC points; MVC gets to do a "re-do" on setting values in the process.
Here at TUG, we have taught each other how to arbitrage these kinds of discrepancies; we buy the SVV Bella unit and use it to reserve Princeville or Maui. MVC cannot stop these internal StarOption exchanges except by buying up all of the inventory, persuading owners to turn in deeds for FlexOptions, or by offering Princeville and Maui owners enough DC points so that if they elect points they can reserve at twelve months instead of the eight month SO window and in the process wipe out their availability for SO exchanges..
I foresee MVC offering enrollment on terms similar to what it did in 2010. Each property and each season will be offered a certain number of DC points which will be set on new criteria (rental value, MF's, scarcity value, etc.) and will hew closer to rental values rather than the current number of StarOptions.
