LAS now has 2 half price tix outlets--functioning much like those in NYC. Tix2Nite is by the large Coke bottle next to MGM and Tix4Tonight is down a bit on the same side of the road just before the Harley-Davidson Cafe. They open at approx 2 pm and sell for that day only and both charge a $4 per ticket service charge plus tax on each ticket and both places handle tix for approx 20 shows. Of course, don't expect to find Celine Dion, O, a major headliner etc but its often common to find:
Crazy Girls, Hail Hail Rock & Roll, La Cage, Neil Diamond Tribute, La Femme, Steve Wyrick, Splash, Showgirls of Magic, Skintight, Tony N Tinas, V, Star Trek Experience

Good Luck--
