One of the purposes of travel is to see "new" sights--I doubt any place in the world has the "glitz" of LAS. You say you've seen AC and Indian casinos--nothing in AC can come close to an MGM or Mandalay Bay in size (from end to end these run nearly a mile)--and most other strip casinos are not too far behind. With the free stuff (Bellagio fountain show, MGM (live) Lions, Mirage Volcano, Caesars sinking of Atlantis), to name a few, should awe even the most jaded traveler. Not too far away is Hoover Dam --worth an excursion. In effect the whole city is a "theme" park. I'd say GO and I'm sure you'll have fun.
