I strongly suspect that the Luxor has a bed bug problem.
1. google search of "luxor bed bugs" returns many comments from hotel patrons regarding bed bugs.
2. I came home full of bite marks after a 2 day stay at the Luxor. Stayed on the first floor. I checked my mattress at home for bed bugs. No sign of them. Haven't received additional bites since my stay at the Luxor.
Bed bugs are easily transferred on luggage and clothing. Be wary.
