Thank you so much for the advice. I'm a little bit scared though because I easily give in to pressure. Are these things in groups or one on one? Because if it's a group, then maybe I can take the heat better.
"The undiscerning mind is like the root of a tree--it absorbs equally all that it touches--even the poison that would kill it." -- TV Show: Kung Fu (1972-1975)
They will sit you down at a table by yourselves with a con artist who will say just about anything to make a sale. They will tell you something to humanize themselves, so you will think of them as a real person. They will ask you about yourselves, as if they think of you as a real person and not just a mark. Then, they'll question you about how often and where you vacation... just making conversation.
They'll use that information to compare how much you spend on your own travel and how much you stand to "save" by buying a T/S. They'll show you that calculation in big, black numbers (often with a magic marker). DON'T BELIEVE IT FOR A MINUTE.
They usually "forget" to include the annual maintenance fees, which alone would cover a one-week stay in a decent (3*) hotel. For the purchase price, you will get a few nice extras, like a kitchen, a bedroom or two, and a jacuzzi, but its not really a "savings." Consider it a donation to the developers capital account. By holding out and waiting to buy resale, you will pay the ~real~ value of those nice extras, and not for the developer's own vacations.
My Approach: Go in with the attitude that the next 2-4 hours of your life are going to be a waste of time, but that you will be patient, let them run thru their script (they all use the same playbook), and wait till they run out of "deals" to throw at you. Do not even nibble at the bait, no matter how tasty it might seem at the time.
Take your own calculator and run some numbers of your own, like amortizing the total cost to own, including maintenance fees and the loss of earnings from a "real" investment vehicle, over a realistic travel life, to come up with the true cost of each year's vacation.
Shake your head and say, "No," firmly, as many times as it takes, even if your spouse says, "But dear..." Then, collect your incentive and head for the nearest coffee shop or pub to decompress, content in knowing that you managed to escape with you wallet intact.
