To be honest I don't know the surrounding streets but the street parallel to liberty bell & Franklin square by the park..i believe it was $6 or $7 for the day.. then again it was the weekend as well. There is one right off the highway when u come off but I think its over $9.
I would say around 8th and arch..you will only have to walk maybe 2 or 3 blocks. I mean they do have kiosks where you can park ..its like 2 dollars and 50 cent an hour. But try to get their early
