If I were an owner, I wouldn't be happy but, I wouldn't panic either. This isn't the first timeshare developer to declare bankruptcy and it's not going to be the last. You can look at what happened to the old Debby Reynolds Resort, Epic, Ramada or Sunterra for reference. All went through major changes but, all of the owners kept what they owned. The big difference was a change in who was managing their resorts.
In the next two years I'd anticpate becoming part of another timeshare group or, at the very least, a new management company running the resort. There will likely be a few rough spots but, in a few years it should even out and might actually improve.
To me the big question will be who's might take over? Who has the cash on hand or the ability to finance this purchase? Off the top of my head I'd say the most likely contender is going to be Diamond Resorts. They're headquartered in Vegas. They had been looking at developing a new resort in conjunction with the Hard Rock Hotel expansion and picking up the unsold inventory would give them something to work with in Vegas again. They have strong contacts in Vegas. They're trying to expand and offer new options to DRI's THE Club members. I'm sure they'd also love to pick up the management contracts at all the old Consolidated Resorts which would provid them additional income. The question is, would DRI have the money? They attempted to buy out Bluegreen but came up short in the financing department.
At any rate I wouldn't be hitting the panic button or worrying about the value or you week. Yes it's a rough spot in the road but, in the long run I think things will work themselves out.
