Valerie was a knowledgeable, funny, friendly, resilient, and engaging tour bus driver. Very friendly and competent from check-in through the grand finale. We learned a lot of Charleston history, building history, streets, mansions, customs, and factoids. Well worth the price and the 90 minutes. If you get a chance to ride with Valerie on a city bus tour... jump on that bus and don't look back. You are in for a ride to remember.
