Cash reservations for
DVC villas are from developer inventory not the condo association (member owned). DVC retains a very small percentage of ownership (it used to be 4% for DVC, not sure if that still stands), but the amount of inventory for cash varies widely as DVC Members use their points for a non-DVC reservation. Non-DVC entities have zero interest in being paid in "points" so the amount of inventory from the condo association that equals the points spent by the member for the non-DVC rez (say a Concierge Collection or Disney hotel, or a
Disney cruise) are moved to the developer managed inventory to be sold for cash in order to pay for the non-DVC stay. It is correct that if MS books the points rez and a member cash rez they can be linked. MS uses a different system from when I worked there long ago so I always add a qualifier in case things have changed somewhat.
I've often had members ask why there is often cash availability for a DVC villa but no points availability. It is because it varies according to how much members are "trading out".
Dean is absolutely correct that any cash rez's made via DRC cannot be linked with a DVC points rez. But they can be cross-referenced as I described in my previous post. And I also very much agree that it is much trickier to match up room types/views, etc., when booking both cash via DRC and points rez.
