When someone does a welcome home visit they do not allow new owners to book a different home resort than they own more than 7 months in advance.
DVC may give those owners a room that was booked on their own points at the home resort…like giving a developer owned room at RIV for a new RIV owner,
But, DVD has to follow the same rules as everyone else when securing rooms using their own points. That is why. DVC doesn’t sell OTU points to others until 7 months out,
No matter what, only points deeded to the Poly tower…assuming it’s a new association…can be used there during the home resort booking period, however that is defined. DVD has to follow those same rules snd once the resort is sold out, DVD would only have the points it still owns…maybe 2%…to even attempt that.
There is no legal way that I can see for PvB and Poly tower to have the same booking window at either one but be different condo associations.
