The Luxor is just plain old cool. My first trip to Vegas, driving in from California at night, that huge beacon shooting up from the 30 story glass pyramid instantly grabbed my attention above anything else. And I was not disappointed when I visited the Luxor the next day.
There's the massive Sphinx out front, and then once you're inside you are in the world's largest atrium. The guest rooms are all around the outside perimeter going all the way up to the top, and I rode the elevator as high up as I could and then looked around to see if I could catch a glimpse of the inside of one of the rooms with the slanted glass walls.
In addition to the awesome look and layout, there are many fun things to do outside of the casino. There is a two-story arcade, the tomb and museum of King Tutankhamen, a great motion simulator attraction, and the very cool Luxor IMAX Theater.
The pool area is quite large, 5 acres in all with four different pools and four Jacuzzis. There is a health club and a full Spa, and even a Wedding Chapel. The 1200 seat Luxor Theater currently (2010) features Blue Man Group. There is also a midnight fantasy show that runs six nights a week. The Luxor is also known for the 19,000 square foot RA nightclub, which features top DJs, nonstop pulsating dance music as well as a sushi and oyster bar and cigar lounges.
There are some awesome dining options at the Luxor. First amongst them is Isis, the all-you-can-eat buffet which frequently wins Las Vegas' best. The Sacred Sea Room is an upscale steak and seafood restaurant with a noticeable wine list. Other restaurants include the Luxor Steakhouse, Papyrus, La Salsa, Hamada of Japan and a 24-hour coffee shop.
There are over 4400 rooms (!) In the Luxor. Personally I would go for one of the rooms in the main Pyramid with the slanted windows. Any of the rooms here are nice however, even the ones in the rear towers. A moving walkway connects the Luxor to the Excalibur, and an overhead "cable liner" connects it with Mandalay Bay.
