We decided to take the Civil War walking tour as we had seen many of the historic homes already at this point in our trip. Savannah was less affected by the Civil War than many other parts of the south. We found our guide to be very interesting. The people on our tour were also very interesting. Many civil way buffs and a couple from England who wanted to learn more about US history. The tour lasted about 2 hours which was just about right. He did stop in several squares to allow people to sit down if they wished while he spoke. I would definitely recommend this tour company. If you are just arriving in the city and want an overview you might want to take one of the other tours--like the historic home one.
