If you're not up to walking around downtown (which can be a hassle, especially when the pavement is so uneven), and if you don't feel like riding in a carriage with horse poo perfuming you with every step, Doin' The Charleston Tours is just for you. You ride in a little mini-van of sorts that has large windows and the tour operator speaks into a microphone so everyone can hear.
You see all the sights and they even stop to let you out a few places to mingle around.
Perfectly fine tour. Do not believe that one has not "properly" experienced Charleston if one does not ride around in bumpy carriages for hours. Automobile tours are perfectly acceptable and actually make the locals happy because those dang carriages are so slow and really hold up traffic
