I just spent two nights at the IP Casino Resort in Biloxi. I was on the 12th floor which is a non smoking floor. I did not smell any smoke ont this floor. My luggage and brief case stayed in the room during the complete stay other than on check in and check out. My shaving kit never left the room. when i returned home and opened the luggage the stench of smoke was almost sickening. I had to leave all my clothing, luggage, shaving kit, etc on the patio to air out. I admit i did walk through the Casino to the confernce room but that was the only time i was in any smoking area. For this room to have smoke residude on the 12th floor is totally unacceptable. If you are a smoker this is the property for you, otherwise stay as far away as possible. I will not use this property again ever.
