Of course I ended up doing this myself....
Today I called over to the Hilton Boston Hotel at Logan Airport to reserve a block of rooms for our wedding weekend. For our out of town guests flying into Logan the hotel has a free shuttle to and from the terminals and also to the water taxi to Rowes Wharf and the Boston Harbor Hotel! The taxi is heated and covered and will be a fun way for guests to arrive to the wedding. I bet N will want to ride around in it "escorting" our guests, but really just for fun! They are putting together the contract to e-mail me and I should be ready to add this accomodation to our wedding website in a few days.
