We visited when my daughter was going through a major Thomas the Tank Engine phase. Thomas was visiting and her grandfather purchased tickets for the ride (I think he was as excited about it as she was). We all enjoyed the train ride and getting to meet one of her all-time favorite characters as well. During the Thomas visit, there were also tents set up with coloring, face painting, Thomas souvenirs, etc. A great "Day Out with Thomas" all around.
We did the Sam's Shortline when Thomas the Train was visiting. This was absolutely incredible and we had a blast! Everyone enjoyed it from the baby to my husband and I. The trains are very well kept and the workers are super friendly. We cannot wait to go back!
The train has different cars to choose from ranging in price. The train makes several stops along the route where you can shop, look at historic areas and includes a lot of Jimmy Carter's childhood and current home. MUST sample the Peanut Butter ice cream! Food available on train or at several local restaurants. The children and adults had a great time!
