I understand.
I dont know how they do it but currently 3 resorts have restrictions when the ARP with CWA can be used, (they block prime times from ARP).
How easily can resorts be added to that list is what I'm trying to figure out.
My guess: those three resorts were all sold as either fixed-week or floating-with-season resorts before they joined the fairshare/club system, and when CWA was seeded with that resort's inventory, they only got off-season/shoulder-season weeks/floats. That makes sense: one goal of CWA is to help resorts that had big imbalances between MF/K based on season---the high MF/K deeds are more likely to default, harder to sell, etc. as standalone deeds. But, blended with a big pool of CWA inventory, it's a lot easier to move the points.
Either way, if the underlying resort is UDI, I don't see how they could add seasonal restrictions to ARP as a matter of policy (vs. availability). If the underlying resort is fixed-week or seasonal-float, there could be, but it would be based on what's in the CWA trust.
And, for those reading along, it is worth remembering that ARP is irrelevant for the vast majority of resorts/seasons/units. For those with a handful of very specific needs, or those who want to follow the Ron P. path, things are different, but they are the exception, not the norm.
