I am going to a conference the first week of April...the conference will have me tied up for everyday that i am there from morning to night. My question is, since I have the option to stay an extra day on my dime (the hotel) is it worth it...and to see/go to what????

I would really appreciate any suggestions...

**I will be at the Hynes Converence Center on Boylston Street and staying at the Sheritan on Dalton Street.
