YEAH< THE AUTO TRAIN!!!
That option would let you take your car! I think it is a little more expensive than the regular train, but you get your car!
We leave out of Raleigh and it's an overnight. So by the time the excitement wears off the kiddos are asleep. Wake up, eat breakfast, brush your teeth, and you are in Orlando!! And you're rested, so no napping at the Hall of Presidents.
