The balance was much different with VGF though. You had past owners of the ~100 original
DVC villas gaining access to 202 additional rooms. (All Big Pine Key rooms were declared into the association very early.)
With Poly, you're going to have owners of the 360 studio rooms all gaining access to the 40 tower rooms at the same time as new buyers. Things will disappear very, very quickly.
Giving early Island Tower buyers any sort of priority booking (over legacy PVB owners) doesn't seem like it would be kosher since they're all collectively part of the same association.
