We have stayed at Luxor the majority of times I've been to Vegas. It is by far my favorite of the hotel/Casino's on the strip. The Casino is great, the ambiance of the hotel is fantastic. It's always a blast arriving at the hotel and the atmosphere is electric.
The food is great (restaurants and room service, not the buffet) and the shops are fun. The hotel connects to both the Mandalay Bay and Excalibur via shopping isles and a walkway (respectively).
The rooms are always clean and well maintained. I have stayed in the standard pyramid king, tower king, Pyramid suite and tower suite and every room was immaculate. The decor was fun and the noise is non existent. While the pyramid rooms do open directly onto the casino floor, you wouldn't know it once you are inside. The noise level only becomes apparent when you open the door.
This place has never let me down. Every stay we've had has been amazing. If you are on the fence, don't be. Take the plunge.
