The applicable rules for future reference: you can use resale points purchased before January 19, 2019 to reserve any DVC Resort that currently exists. As to resale points purchased on or after January 19, 2019:
1. Such resale purchasers of "new" DVC Resorts opened after Jan 18, 2019 -- currently Riviera, VDH and CFW -- can use their points only to reserve a room at their home resort.
2 Such resale purchasers of any DVC Resort opened before Jam 19, 2019 can be used to reserve those resorts, including any addition made to those resorts after Jan 18, 2019, and thus can be used to reserve the additions that have been made to VGF and Poly since 2019.
