One of the other ways to get out of a presentation early (rather than having your kids trash the room!) is to tell the salesperson that you know about resales and how you can buy a Hilton week that way for under $5000 (we paid $2000 for an excellent non-Hilton week, bought Hilton from Hilton). If yours salesperson isn't a real sales weasel, they'll get the point that you're not going to be buying & make the tour brief..(but if you get a jerk who thinks they'll make a sale at any cost, I've seen them go into high gear at that point..it works in most cases though)..
