Luxor isn't bad... BUT it's all the way at the end of the strip. You have a bit of a hike to get to the tram that'll take you to the other end (tram is located next to Paris, LV). If you want a central location, check Paris, Bellagio, Ceasars Palace. Even New York, NY or MGM Grand. Luxor is cool, but a pain in the ass to get from one location to the next INSIDE... and good luck finding the elevator that takes you to your floor. There's elevators, "inclinators", and stairs that never lead you to exactly where you want to go. There's also a cheap little chain fast-food food court... if you can find it. We were there for two days before we realized there was a cheap food court.
If you want a themed place... Luxor is good. If you want a place that's conveniently located to everything else... look further up the strip. The Mirage actually seemed pretty cool. Don't go too far up the strip though... old Vegas is some run down shit.
