I really like the Luxor but it's one of the more smokey of the new casinos. We gambled here for a few hours before seeing the Criss Angel show and I had such a bad headache from all the smoke I had to go back to our hotel room and lay down.
The Luxor is cool with the pyramid shape both outside and inside - from the main lobby and casino area you can see up into the pyramid.
The casino has tons of places to eat, shop and game. It connects directly to both Excalibur and Mandalay bay via walking tunnels as well as a tram that runs all day every day between the two until 11pm or so.
My favorite Mexican place, Tacos and Tequila is just off the escalator in Luxor - it's small but delicious and they have the best pulled pork burrito ever.
There is also a Titanic and Bodies exhibit just beside the T&T place. I've seen the Bodies exhibit (it's been several years) and thought it was fascinating.
We have never stayed here but always stop in when we're in Vegas. It's worth seeing - I hear the rooms are pretty nice but I can only comment as a day visitor.
