While the current contract structuring probably precludes it, why couldn't DVC roll out a 'lite' version of the club (think less expensive buy in, accommodations along the line of the family suites @ the AS value, i.e., 2 units converted into one)
perhaps a 3:1 point conversion factor would work for these owners to cross over to the current DVC point scale and the reverse for existing members to downscale @ slightly shorter than current 7 month window (4 months out?)
Can't say i've ever visited POR, but we selected it for FD in Dec, looks lovely, especially the lush landscaping
From what i gather the Riverside section is huge. Why not take 1/2 of the resort (bayou?) and just re-configure the existing hotel rooms with just the right Disney spin to make them different from the standard rooms...
nemo, pirate, princess/frog

, whatever
IMO, wouldn't cheapen the brand if it's designated as separate tier of membership. It could be easily be implemented @ any of the mods.
