I think a timeshare, especially a fixed week you have been utilizing for decades, is something that you can't compare to a store or restaurant which has other viable local options.
In the case of Jamestown, them substituting CWA gives them more flexibility to vacation elsewhere, but it absolutely cannot replace their local option that no longer exists. There's no way a fixed week June or July owner at one of the Jamestown resorts is going to be able to book at any of the Newport resorts in June or July. It's just not happening. Similar for people wanting to substitute, say Smuggs for BB, with CWA will you be able to book peak ski season in Jan/Feb? I don't know, maybe, maybe not. A larger number of people are now competing for those same finite number of units at Smuggs because BB doesn't exist.
Can they vacation elsewhere? Sure. Maybe that helps them, maybe it doesn't. It will vary person to person.
But comparing this scenario to a store, restaurant or hotel is not valid. It's just not.
