As I mentioned above, I had a cold during most of my stay in Las Vegas. The Mandalay Bay, like most Las Vegas hotels on the strip is not a healthy place to be. The casinos are smoke filled enclosed dungeons with no windows and completely lit up with artificial lighting. The overall energy there is not healthy either. The hotel blows cold air throughout the casino and room areas which is also very unhealthy. So we decided to take a short walk outside the hotel in order to get out of the sick environment. It was unseasonably cold outside, but better than being inside. While outside I took a picture of the hotel's signage. In the background you can see the Luxor.
