I just bought a round trip bus ticket to Philly for $43...gonna be a long ride but it will be an adventure, which I will like. It goes from Boston to New York, then I have a 45 min layover for the bus to Philly, and from the Philly bus station I'll have to take a taxi to the hotel, which is near the school so I won't have to rent a car. The hotel will be $100 with a special deal (onebigcampus.com); which is a little expensive but I tried looking at Philly's version of the T system and it was a little confusing. But hey, going to Philly and back for less than $200 isn't a bad deal at all!
