I need a little getaway from my job and since I have never been to Philadelphia and it is not to far away I was thinking of flying down for 4 days in April. Since I do not know the geography of the city I was wondering if you all could help me. Where is a good place to stay that is reasonably priced (hopefully $150 and under) and is close to all the major attractions? Also what would be the major attractions that I MUST check out? I am a 20 something female that will most likely be traveling alone if this makes any difference. Any information you can give would be greatly appreciated!
