Since I'm actually only one (full) day in Boston ...
Well, at first I'd thought to book a
guided tour on a bicycle. The photo tour seems to be a bit expensive, but just a bike sounded good ... until I noticed that I hardly can take my full photo equipment with me.
So, a bus tour. What about
Boston Tours? (No, I'm NOT keen on Duck Tours!!!)
Or should I better stroll on my own (especially, since I certainly will have seen quite a bit of Cambridge before we'll meet).
