in one of the casino parking lots in Atlantic City, be sure to get a receipt which you can then use as a "transfer" to get into a parking lot at another casino without having to pay again. It is a one time use transfer only and must be used by 6am the following morning. If you do have a players card, you may well be able to park for free at the casino where you have the card. Harrah's properties in AC include the Showboat, Caesars, Ballys and Harrah's so one card will get you into all those lots.
