or players cards..not sure exactly what they are called.. I am trying to figure this seeing as I have never been to Vegas. So each casino has some sort of a counter or something that you go to and sign up..then they give you a card? Am I correct that you then scan or swipe this card when you go to play??? I know some properties are owned by the same company..so you only need one card for each group of casino's? Just wondering how many cards I will end up with Should me and dh each get one?
