The very fact that you are asking questions from strangers on a forum should be a gigantic red flag. You obviously have doubts. If you wait, you will be locked in. If you rescind immediately, you can still get out of this deal. Then you can ask all the questions you want, and not be pressured to make your decision under a deadline, BELIEVE me when I say that the "deal" you received can be purchased from them again for the same price if you still want to down the road.. Dont let them get your hard earned money without you doing your due diligence first.
The secondary market is PENNIES on the dollar. Timeshares that were sold for thousands or tens of thousands are available on resale market, some free, some for a few hundred, some still have a value but at a 10th of the price they were originally sold for. Dont be another sucker Danny!
Btw, a common theme we hear from people "trading" in their timeshares in mexico, is months after they purchased their new timeshare and have strapped themselves with another financial burden, they find out they STILL own the other timeshare! To you and future readers of this thread, Make sure you have this in writing! Nothing verbal matters, if it is not in writing it does not exist.
