I think everyone is just rolling over and accepting this as a done deal which it very well MIGHT be...but...anyone can put anything in a letter and send it. It doesn't mean "the SXM Government" weighed in an approved it nor that the courts would uphold it if asked to become involved by those affected.
If anyone really wants to fight this I would think a signed right of use agreement for x years would be on their side. If THOSE agreements have no value then any right to use (not deeded) resort could "change hands" every few years and eliminate all purchases made and start over....and over....rinse and repeat.
I have no chips in this resort but it will set a precedent for all right to use "Vacation Ownership" aka "timeshares"
