I have heard stories like this before but this is a particularly scary one.

I have heard those stories about people following big winners home from the casino to rob them, but I have been actually more concerned about something like this. At least if you are being followed in your car you can call police or drive to a police station. Once in an elevator not much you can do, especially alone. I also don't mind if they have security checking your room key, but other than the Boyd casinos I don't know of any others who do it now.
