Still unsure if this is true or not (since no one can get the same answer), but if it is, here is how I see that it works.
There are technically three types of ownership entities in this.
- Legacy non-enrolled weeks owners
- Legacy enrolled week owners
- The Trust (I don't indicate trust owners, because the trust is just another enrolled weeks owner)
Then you have the Exchange Program that all owners exchange through in the new program. The Exchange Program is a separate entity from the trust.
- When a non-enrolled weeks owner wants to make an exchange, they do so as in the past, through II. No changes.
- When a trust owner wants to make a reservation at a trust resort, they just make the reservation. This doesn't go through the exchange program as long as the trust still has inventory for the requested resort.
- When a trust owner wants to make a non-Marriott exchange. The exchange manager deposits a week in to II equivalent to the points given up for the exchange. This inventory doesn't go through the new exchange program.
- When a trust owner wants to make an exchange to a Marriott resort not in the trust. The trust makes available to the exchange program the number of points that they are exchanging with and the trust owner gets a week that a legacy enrolled owner deposited/converted for points. This same number of points now become available in the exchange company. Legacy weeks owners can now reserve via the exchange company for resorts in the trust equivalent to the amount of points that the trust has deposited to the exchange program.
- When a legacy enrolled weeks owner converts and wants to exchange/reserve for any time, they can only reserve for inventory in the exchange program. That inventory is made up of weeks that were converted to DC points (perhaps also MR points) and points that were deposited to the exchange program. Legacy weeks enrolled owners can't access the points trust inventory until the trust makes it available to the exchange program.
The exchange program is a points in points out system. The trust and legacy owners put points in and then take time out. Trust owners can't access inventory that are not deposited to the exchange program, so I can see why enrolled weeks owners can't access points not deposited to the exchange program either.
This is all speculative and my analysis of what I have read in this thread.
