Great trip; very well timed so that we did not feel rushed but also were able to get sufficient time at each attraction. The visit to Ft Sumter was most instructive and absolutely a feature of trip #7. Also, because we were one of the earlier carriage tours, the market wasn't as crowded as it is later in the day.
The only negative is the box lunch that is provided; given the cost of the trip a nicer box lunch should be provided. No name turkey on white bread (think, wonder bread) and no name look-alike Oreo cookies doesn't cut it. I would recommend bringing your own lunch and snacks.
However, other than the lunch, this is an excellent trip.
