Myself and 5 other male friends are planning to travel around the East Coast for 3 weeks at start of August. We have first 3 nights booked in NYC and think we are going to visit Boston and Atlantic City. We are all in our young 20s so we would like to see plenty and have a good scene at nightime wherever we go. We are prepared to take a short-haul flight to get to other cities, Miami and Orlando have been mentioned, but not many as budget is restricted. We stayed a summer in Philadelphia/Washington so have no real interest in visiting there again.
Any suggestions on destinations are welcomed?
