Long ago when we used to do the drive, from northeastern Ohio, straight through stopping only for gas and restrooms, it was 19 hours.
Those days are gone, too much traffic, semis, big cities and alot of time.
We have been taking Amtrak for over 8 years now, its 26 hours with layovers but a heck of alot less stressing, no wear and tear on the auto, we eat and reststop on the train and we use our bonus rewards to up grade to a roomette on the long legs of our trip. Even when we used to drive, we always used Disney transportation on property. After driving like a crazy man for 19 some hours, driving around Disney was not my cup of tea. Think thats why we like Disney so much, they haul you everywhere on their dime, no fuss no muss for me.
