There should be no problems in you being able to get more than one players card if you are going to be playing more than one slot or video poker machines at a time, you will simply need to ask at the comp club desk for an additional card if you want one. Do however make sure that you insert the card into each machine you are playing and the card has been registered, if the card has not been registered by the gaming machines you are playing you will not be accumulating comp points and will not be able to claim them back from the casino either!
