We did the timeshare sales pitch one year (about 6 years ago) and it started out ok, had a cocktail talked with a few guys, etc... I kept saying we most likely are not interested in buying until we've been here a bit more often. They escalated us up to one of the owners, a british guy, and it quickly became more and more pressure. He rambled numbers and locations and was basically telling us this was the best deal around and we should sign on. I told him for the amount they were talking I would rather look for something to buy or even build... yikes he came unglued and was yelling and telling me I would never come out better than his deal.
After an hour of him, I said we were done and I wanted the $100 they promised us for listening. He then tried to switch me to a free week another year. We stayed tough and did eventually walk out with a $100 bill. Now trying to get a boat taxi back, no one was interested in helping us... we walked to another resort and caught one later. For me, never again, no timeshare sales pitch is worth my time.
