Another way to quickly end the meeting is to tell them you are on your honeymoon. Obviously this might work better in Hawaii than Orlando... Seriously: we did one of the deals with HH on the Big Island, and told the guy it was our honeymoon (which it actually was).

The salesman laughed and admitted that in his 25 year career, he'd figured out that honeymooners never buy. He gave us our "credit" without even doing the dog & pony show - we were out of there in 15 minutes.

To the point at hand: Marriott's timeshare presentations are tasteful by industry standards. Yeah, you will have to say NO a few times, but I wouldn't compare it to a company you've never heard of out of Atlantic City that probably uses every dirty sales trick in the book. I've done a couple of Marriott timeshare tours: they are not that bad.
