I'm going there for a conference in September. In the weekend I planned to meet up with my girlfriend in Boston and stay there till Monday. After reading this though, I'm thinking we would be better off in Cape Cod. Also the hotel fares in Boston are pretty steep.. a Super 8 in Boston costs about the same as my nice hotel in Hyannis.
edit: I got that last bit wrong.. I called the hotel now, and they want $170 for the room as opposed to $94 during the conference
