We have 6 yo, 4 yo and 18 month old children and are heading to Disney in November. Our drive should be 10-11 hours from central NC. Last time we took Amtrak overnight in a sleeper car and nobody slept much. This time we are driving. For driving veterans which do you find easiest: leaving at the kids' normal bedtime and driving all night praying they sleep most of the way? Or, driving during the day?
