This is Graduation Weekend in Boston.. BU, BC, MIT, Harvard among others are all in the general area have Graduation events going on, so many out of towners have taken up the hotel rooms. Hotwire and Priceline are your best bets.. If you can find a hotel on the MBTA line, the get it, it's a breeze getting to the park via train. I still haven't decided if I'm going or not..
