Where to stay near Philly?

[ColemanCampingFamily]

We are making a last-minute trip to Philadelphia week after next and need to know a good, safe campground to stay in. We can either take the PUP or go tenting, but electricity is a must either way.

Our "plans" include visiting the Liberty Bell, etc. and anything historic. We will be spending a limited amount of time at our campsite, but a nice hot shower would be nice.

Since we are on a quickie time-frame, any and all advice is much appreciated.

We stayed near Philly last year.  There are a couple of Passport America campgrounds north of the city about 30 miles or so.  We stayed in one of those, I don't remember which one.  Go to the Passport America website, you can look them up without being members.  IIRC, there wasn't much anything closer that we wanted to consider.
