We've been using the train to WDW from northeast ohio for about the last ten trips, 29 plus hours. We have no problems other then it being late but I do not like flying and driving is too hectic and stressful. Amtrak has its ups and downs, as stated above the seats are huge, plenty of room. We've down the whole trip in coach but prefer to do the first leg, Alliance, Ohio to DC coach and from Dc to Kissimmee, we get a roomette, it includes meals, its a very small room, just for two but at least you can lay down to sleep, we arrive in Kissimmee around noon, refreshed and ready to go. Usually runs the two of us $450.00 round trip and the cab fare from Kissimmee depot to say Poly or Wl, runs 35-38.00 plus tip.
We through in a car trip couple of trips ago, 1150 miles, and that was enough of that,, same time frame, about same money, room and gas but too stressful with the traffic. We waited to long to book the train and had no other option. Now we book early for the train. Its not for everyone but for us its very relaxing, peaceful, mostly, and gets us there.
