Well, considering BCV only recently sold out, one would certainly HOPE that a buyer wouldn't make such a big decision only to reverse it 12 mos later! (No return on investment there, for sure)
We've owned at BWV since '99 and my sister has owned at OKW since '93. ANd in those years, we can each name plenty of our friends who have gotten divorced, or lost jobs, or become medically hindered, or found new expenses, like college tuitions, or changed their whole vacation concept (they travel less or closer to home). Some folks have a 9/11 attitude and just don't want to go to "big spots" anymore. So if you look at our narrow slice of demographics, one would have to believe the same would be true amongst our fellow DVC friends. Stuff happens!
Or put another way, Life sometimes gets in the way of livin'. And DVC is a luxury item (tho' many of us might label it a necessity!) And lots of owners who might find themselves in a situation to sell are owners of more than a few years (OKW, Vero, and yes, BWV.)
And after all, if all those BWV folks were just out to buy OKW, there wouldn't be any OKW listing available, now, would there?
Before you slam or poke fun at any resort, remember, there are lurkers out there, gathering data on which resale to buy! If they all buy at OKW, just think of the grief we'll endure when Richyams finds he can't get his OKW GV anymore and has to (gasp!) stay at one of those "tiny" rooms down the long, ominous hallway.
I shudder at the thought.
