Because of the Tour Lottery system the City operates, you don't know where your tour is going to go until you're on the carriage. We got Tour #3, which goes along the Ashley River and takes about an hour. Thank goodness they had a blanket on each seat as it was cold and windy along the river. Our guide was good - very informative but not a ball of fire; maybe you'll get a more entertaining driver as we saw several in the stable and around the parking area where all the Carriage Tour companies start.
Keep your eye open at your hotel or anywhere they have the little Tourist Things To Do racks - we got a $3 off per person voucher, which brought the tour down to $19 per adult.
