My wife and family went to PA last year for Spring Break and some attractions we saw were Gettysburg and we highly recommend you getting a tour guide who will drive you around and explain everything! This was very helpful because we saw everything they showed us, but explained it in great detail, which we wouldn't have known without them. Not sure where your coming from but if you will be on the turnpike, stop off where the Flight 93 memorial is, very humbling and awesome experience! Definitely go to the Eastern Mueseum! Have fun!
