Worried about going to Fort Jackson

The only thing I ask is that I get the opportunity to see my son graduate from Fort Jackson, I know that I will have to attend his graduation from AIT as well. A friend of mine told me it takes 15 hours to get there. So I need to plan what I will do with the children so they don't get bored until we arrive to our destination. It will be a little hard but I think we will be ok.
