Hi, we have a week where we are driving from South FL to Nashville, TN. We need to be in Nashville for 2 days but other than that we have no specific plans. I am clueless on what to do in Nashville with our kids (15, 12, 10, 9) and where to stop on the way there are back. We don't mind driving all in one day...but not sure what to in Nashville with our kids. And...we aren't sure where to stop on the way up and back and things to do. We are not use to vacations like this...we have only taken cruises with our kids, this type of open vacation is making me lost! We are traveling to Vanderbilt University to visit our cousins. Any very specific advice would be greatly appreciated!
