They cover that in their sales pitch. There's supposedly a market for trading timeshares, so you can trade in your timeshare for someone else's, specially if you have a highly coveted one
Of course none of it is as easy as they make it sound.
Yeah I also got dragged into one of those while on vacation in a timeshare property in exchange for some tour tickets. The tactics are truly despicable. They insisted that me and my wife shouldn't talk to each other in our language because "it's not polite". We didn't speak the local language very well (although we could understand it), so this was obviously to keep us from talking to each other and be more vulnerable. They tried to waste as much of our time as possible in the hopes that we just sign the damn contract to get rid of them and enjoy our vacation.
I'd never heard of timeshare back then, but luckily the deal sounded really bad anyway and we were very adamant on not making any decisions under pressure even if it meant losing this "once in a lifetime offer". In the end they begrudgingly gave our tickets to the tours and ushered us out.
The writing is usually on the wall for a while before the layoff actually happens, so there's time for you to let your manager know that you wouldn't mind getting the boot.
