Need help from Boston people

[Bryce]

My wife and I are going to be taking a trip to the NE this June.  I know there's tons of Boston area people on the boards -- can I get some advice on where to stay, where not to stay, things to do, etc in the Boston area?  We're likely going to have three full days to spend there until we head up to Vermont.  We were both history majors in college so we're looking for cool historical stuff to see, which I know there's tons of in the Boston area.  

 

Thanks in advance for any advice you can give.  Feel free to PM as well.
