If you don't like cities, crowds, and construction, stay on the ship. We got off the ship and realized we'd have to walk about 2 miles before arriving to almost anything worth seeing. So instead of getting back on the ship, we opted to get a trolley tour of the city and area. We didn't do the most popular trolley tour and instead chose the big green bus. I'm so glad we did. The bus was much taller than the trolley so we could see more! It was an hop on/hop off tour which we enjoyed. The drivers on these buses were comical and well-educated about Boston and it's history. That bus tour ($25 pp) also included the FREE Harbor Tour AND a FREE Duck Boat tour!!!! Can't beat that bargain. We stayed on the bus for the entire loop then got off at the Constitution stop. Got back on (waited only 3 min for the next bus) and got off again at Quincy Market. OMG, it was packed full of people! I don't like crowds so we grabbed a bite to eat then started to head back to the ship. Unfortunately, the trolleys only go in one direction and Quincy Market was at the beginning of the loop. The only way to take the trolley back was to go through the whole loop again (about 2 hrs). We opted to walk back to the ship, which was about 2+ miles and about 45 min., give or take since I was taking photos. All in all, Boston was a port I would skip the next time and just stay on the ship. I hate enormous crowds (like Quincy Market) and heavy traffic. If you don't mind that, you'll probably enjoy Boston as a lot of people did.
