My family and I (husband and 2 kids aged 2 + 4 yrs) are making the drive from DC to Kansas City. What I am trying to work out is whether to do it in 2 nights or 3? If 2, do we try to make our way to Indianapolis and then St Louis? Or if we go 3 then do we go Columbus or Cincinnati and then Indianpolis and St Louis? Help me? We also have to make the trip back and then where do we go to get home?
