I also read that you can get a transfer receipt, drive to another casino, and show the receipt for free parking. I've read that you can park at Harrah's for $5 for your entire stay with in/out privileges.
I've been reading here about options to get from Harrah's to the Boardwalk (shuttle, jitney, taxi, driving, etc), and am a little bit confused about the driving/parking option. This time, we're thinking about staying at Harrah's. I've visited Atlantic City twice, but always stayed on the Boardwalk.
