Everything happens at least twice. There actually is an established industry to supposedly help folks get out of timeshares.
Asking because someone in my extended family owns a timeshare and got scammed with an exit offer. It sounded similar to the timeshare pitch itself.
Maybe my opinion is biased (the media generally does not publish "everythibg is a-OK" articles), but my perception of the timeshare escape industry is that they are sketchy too.
I think this Last Week Tonight episode is very informative on the topic:
Timeshares: not even once.
