High atop The Hotel at the Mandalay Bay Casino and Resort, at the Mix Bar, is a bathroom where a lady can relieve herself while looking out over the lights of Las Vegas 64 stories up.  Of course my sisters photographed themselves doing just that, because they are crazy.  It should be noted that the urinals in the men's room are set against a plate-glass window offering a similar view to gentlemen relieving themselves.  It adds interest to the procedure.
