On our last afternoon in Vegas I suggested my friend and I head to MGM since we hadn't been there yet, and because I'd heard about CBS Television City and figured it would be a fun way to kill an hour.
This is the place where you get to be on a panelist that decides the fate of upcoming tv pilots. We were told the entire experience would take about an hour, but if you finish the survey quickly it might take less time for you (I was done in about 45 minutes). Essentially you watch a tv pilot, and while you do you turn this dial in front. It goes from 0 (you hate it) to 100 (you love it), and after the show you answer some survey questions on a computer. When you're done you're give an envelope with some coupon vouchers, including one for $10 off the CBS Gift Store (with no minimum purchase, so it's a good deal). If you're getting tired of the casinos and want something else to do in Vegas check this place out.
