I've been reading many helpful posts regarding what to see and do in Philadelphia. We (4 adults) will be driving to the area, is parking an issue? Do most of the hotels have parking or is it an extra fee? We want to be fairly close to Cooper River Park, NJ. If we stay in Philadelphia about how long of a drive would this be? (miles and approximate time) I read one message about staying in Maple Shade, NJ - what are the pros and cons? I have lots of questions - I am looking for something reasonably priced, but nice and in a safe area.
