The resale points bought now would be restricted to L14 for your use. If you go to sell them, the new buyer will be under whatever restrictions are in place at that time.
Right now, we know for sure you can’t use them at RIV and any future resorts.
What we don’t know for sure is how DVD will define DLT and the new Poly tower. We assume DLT will be considered new and restricted to resale contracts bought since 2019.
The new Poly tower is a mystery and it could go either way. So, as I said, IMO, assume it will be new and restricted from use with the new points.
This way, if it ends up in the same association as the current Poly, resale points will be eligible there!
