There are a million time shares. Buy new or buy used. I can't see much difference...
except for price. And that 'weeks' are not really being sold, as they prefer to sell you points.
First, take a look at your annual fee. I pay under $300 per year.
I have 1 week a year, can use previous unused years, or borrow from future. My initial purchase price was less than 1/10th of what you quote.
I think it's a rip off. You decide for yourself.
