Hi tekoa
We have traveled via the AutoTrain many times. Personally, we love traveling on the AutoTrain. Neither DH nor I are overly fond of flying and hate the 17-18 hour drive from PA. That being said, you will find that most people either love the AutoTrain or absolutely hate it. Our experience is that it is a way to relax before the trip. We have been delayed up to 3 hours a time or two. Some have experienced much longer delays, it is not the norm, but it can happen. Just as flights can be cancelled or delayed at the last moment. Things can happen when you travel. We have traveled coach and in a roomette. DH prefers a roomette, however if cost is a consideration, we travel coach. DH is 6'2 and I am 6', and we don't have any major problems traveling in coach. Normally, there are enough seats that each person can take up 2 seats. The food that is served on the train is decent enough. Not gourmet or 4 star, but it is tasty and filling. You have a choice of one of 4 or 5 entrees, salad, dessert and beverage. There is also complimentary wine served at meal time if you wish to imbibe.
Our next trip on the AutoTrain is in early November and i am looking forward to it as always.
