Just joined the group and looking for advice. Planning a driving trip between Christmas and New Year, probably 6 to 7 days total. I'm in Chicago suburbs and would like to go south. 2 adults 2 kids. Right now, thinking maybe stopping in Springfield IL, St. Louis, MO, Nashville TN, Louisville KY. Nothing definite. Is this doable? Are there other places that are better stopping points so I don't stop at the same place on my way home?
