I decided not to book this tour as there are at least 2 days in Falmouth that could have been used to see other towns in the vicinity. I would have said Plimoth where the Pilgrim Fathers landed, Mystic, Martha's Vineyard and more of Cape Cod.
Having done this with my daughter, I loved it including more time in Boston, visiting Harvard University which we went to on the Metro. Also went up to Salem and learnt all about the witches.
