This morning at 9:00 we took the KOA shuttle to the commuter train station, where we boarded the "T" for Boston's South Station. Then we had to walk four long blocks to the Red Beantown Trolley station. By the time we had actually started our tour of the city, it was around 11:30. At the suggestion of the KOA desk clerk, we rode the trolley without getting off at any stops.
After we had returned to the trolley station, we ate lunch at Quincy Market. Then we took the harbor cruise, which was short and sweet. After that, we didn't really have time to visit anything else, so we walked back to South Station.
We may go back later this week but we will drive ourselves to the train station early enough so as to arrive in Boston with enough time to actually visit more places.
