I am looking to go over to the states in May time to visit friends. I will be flying into Washington spending a couple of days there before going up to visit friends in Philladelphia. I will be on my own and thought I might use the extra days about 5 in total seeing another city or two. Having looked on megabus.com I can get to ; BALTIMORE, BOSTON, ATLANTIC CITY in a couple of hours
Any reccomendations? Or would you reccomend anyother cities in the Washington/Philadelphia area
