I predict we will find out when they announce whatever it is they plan on announcing.
However, if I had to make a guess. I’d say that they will assign DC point values to vistana weeks. Values will be based on resort, unit size, season, and view. Points based ownerships like flex, nanea, Aventuras, etc will have a conversion rate. I’d think that all developer purchased ownerships and any ownership that was retroed would be eligible to convert. If it’s not a a retroed week or it’s it’s a resale, you’d have to make an additional purchase to be eligible. I also think that vistana owners will have to elect to convert to DC a year in advance. The underlying week would come out of the VSN and into the DC Exchange. This will help fund the inventory pool for MVC owners to book Westin properties (this is where the skim can be applied as well). Eligible Vistana owners would have multiple options in using their VOI. They can book their deeded week (Home options), 8 month booking via the VSN, Exchange in the DC, or Deposit in Interval.
I don’t see much in terms of changes for Marriott owners. Those eligible to book with DC points would still be eligible to book with DC points. They would now have access to the Westin/Sheraton properties that are deposited into the DC.
***If MVW has plans to do away with Vistana (VSN) in the future, things get tricky. This is where mandatory resorts would need to be in some sort of club. Would the DC be the new club and If so would resale mandatory ownerships have to be included?
