Well, as far as actually having an effect upon our DVC ownership...the only thing it may change is resale value...most timeshares lose 50% to 70% of their value the minute you buy them. DVC is the exception, and the fact that DVC has ROFR as an artificial price support helps.
The resorts themselves could be changed to an outside management company, like Marriott, who is experienced in upscale resort management. Points required per resort are pretty well set in stone. The
point charts could be adjusted, just as they can be now, to up some rooms and season but they'd also have to lower others...the overall point total can't change.
Parks, if a new owner wanted to make a quick buck, could sell off park operations to Six Flags or Cedar Fair (Cedar Point's parent), OR they could continue to operate the parks.
It would depend entirely on WHY they want to acquire the company, and what their long term vs. short term goals are.
