Kevin was an excellent driver and guide, he went above and beyond to accommodate my wife and myself to make the day as enjoyable as possible. The optional trolley option is essentially a must in hot weather, many of the attractions are along a stretch of several kilometers. The cruise option is a nice break with some decent views, but perhaps this time (about 70 minutes) could be better spent on some of the other many attractions and museums. Be aware that most of the main attractions have additional fees, including the fort, which is part of the US national parks system. We had just over 6 hours of free time in the city, which is enough time to enjoy a few attractions but certainly not everything the city has to offer. All in all this was a great introduction to the historical city with a great driver.
