Wyndham used to include the "VIP" benefits on resale, but discontinued doing so. The drop in resale was modest because the market has (correctly, IMO) determined that the VIP benefits are worth little---perhaps 10% of retail pricing. Other systems (like Starwood's) do have a much broader split depending on whether it's a Mandatory resort or not, and TravelShare seems to have had a significant impact on WorldMark resale pricing. I'm not certain, but it seems that Bluegreen's "authorized resellers" command only a modest premium, not a significant one. Diamond/Sunterra is the system I'm least familiar with (and with the various forms of Club/Trust deeds, possibly the most complicated.)
