Makes no sense to use a plane if you're afraid to fly.... Nothing's going to get anyone over that hump....
We all know the time difference between flying, driving an using the train.... Another moot point!
I don't fly, we drive and use the train, Amtrak... To me it's senseless to use the Auto Train-- cost of taking your car negates saving money, same with using a sleeper ... For one night on a train , easy to sleep in coach and as for using the AT, cheaper to rent a car in Florida than hauling yours on a train.... No car is needed for a WDW vacation...
We use regular Amtrak from northeast Ohio, layover in DC for south bound train.... Easily sleep in coach, we pack sandwiches, snacks and drinks and lie back and watch the states roll by...
If you're in a hurry, like flying, by all means fly... For those unaccustomed or afraid to fly, Amtrak is a great alternative, get a chance to see some of the country, lie back and enjoy a good trip and the company you brought with you!!
