You can still buy HH and VB resale in this price range. As I noted, we're not there for HH & VB even at this point so to justify an off site on this basis will take quite a few more members, certainly more than any planned or rumored on site resorts. Even if AKV is finished and sold, CRV and DL; that wouldn't even begin to to approach the number needed.
DVC has soured on off site locations, in spite of some of the rumors, I wouldn't hold my breath. Personally I hope they build 20 off site resorts but it doesn't make sense from a $$$ standpoint. The truth is that DVC is unwilling to compete in a timeshare sales world and thus far, unwilling to pay the big bucks for the few remaining top spots in high demand areas like HI, Aruba or even HH. And they seem unwilling to establish a new destination site as Marriott has done with Ko Olina on Oahu for example.
