I don't know if you literally mean that or if that's hyperbole (exaggeration). If you literally mean that, then I have an even lower view of TS sales people.
They don't check to see if potential buyers have the means to purchase and keep up with the MFs. All they care about is making a sale. So you break the bank buying an interval but, because you're now homeless and probably jobless, you can't afford the MFs and, hence, can't afford to use the interval that you just paid tens of thousands for.
It's an exaggeration. But it's a huge money to me cuz I'm a only a graduate student with monthly stipend. I have some savings but after paying all the timeshare money, I'll lost 50% of all my savings, and I got a wife, too.
