In Savannah, my kids enjoyed dinner at the Pirates House. Also, ice cream at Leopold's Ice Cream (a well-known ice cream parlor) was fantastic. We loved walking along River Street, which has nice little shops and restaurants. Forsyth Park is beautiful (that's where the famous bench scene from Forrest Gump was shot). There are a bunch of different museums. We liked the modern art museum, the name of which escapes me at the moment. Just seeing all the squares and the history is beautiful. They have ghost tours that might interest your kids if they are into that sort of thing...not sure if they are too young.
