We stayed 2 nights and I don't know if we became accustomed to it or they cleared the air, but we didn't notice it again. The air was better, but smoke was noticeable.
We went back outside and entered the hotel entrance. Although the doors said no smoking, the secondhand smoke hit us in the face (we're from a no-smoking-in-buildings state) they have a smoking gaming room and a nonsmoking gaming room-the entrance is between them. When we first arrived, we entered the casino entrance unknowingly. The shower pressure was adaquate, but we would have preferred more under the warm water-it was fine under the cold. The pillow top bed was firm and comfortable, giving us excellent sleep.
