I know that a lot of Strip Hotels state on there website that you have to be a guest to use there pool. But do they really regulate it? I have stayed at the Tropicana many times and have never been asked by anyone if we were a guest or not. It is a very easy pool to gain access too. My Wife and I were planning on visiting a few different pools to see what there like.... I have heard that at Mandalay Bay you have to show them a room key to gain access.... is this true? Any info on this subject would be greatly appreciated. Thanx!
