Excellent! Very interesting and even though I'm a nurse I still learned a good amount. We purchased the accompanying audio tour...not really worth it in my opinion. Even if it was only $6. The few guides that were in there were more than willing to answer questions although we really didn't see them until the last room. But they were knowledgable and seemed to really enjoy their work. Definitely a must-see! And there are coupons for $5 off admission for up to 4 people in some of the Vegas books. I think the Luxor should offer a few more bucks off for guests of the hotel.
