I just got home from an Amfleet trip on Wednesday. I don't know if the seat was a I or a II but I didn't find it very comfy for sleeping. It doesn't recline far enough. It does have a leg rest, but to put it up you have to get up, push a lever down and physically reach down and pull the leg rest up to the position you want, then crawl in over it. There is also a little bar type foot rest that is connected to the bottom of the seat in front of you. It's nice as your feet hang off the leg rest and that gets uncomfy after awhile.
The seat is fine for sitting up and reading or watching the scenery, but for sleeping it leaves a lot to be desired. the cushions were blue and very flat. (not thin, but flat as in no curvature)
I bought a travel pillow at Walmart for $3.00 - very good investment. The little pillows they hand out on the train are tiny and not very thick. We weren't offered any blankets but I brought my own - it's a small travel blanket that I received as a gift from my workplace - came in real handy. I also brought a light fleece jacket. It was quite warm when I got on the train but at night it was freezing! My jacket was great to have. Kept me from being a popsicle! (and my nice thick socks I brought too). I have a smallish "hobo" type carryon that I put the pillow, blanket, book, magazine and snacks in. Easy to carry.
Every couple of hours I would to to the cafe car, get a drink and sit there for awhile and read my book or watch the scenery. Gave me a good rest from the coach seat.
There were two bathrooms in each coach car. One was a little larger than the other and had a "transfer board" for people in wheelchairs. Nice touch. Both are roomier than an airline bathroom. but just like on an airplane, whenever I go in one they always hit a rough patch of rail or go around a big curve, rofl. Overall, I like the Amtrak bathrooms.
The attendants and conductor were all pleasant, the people working in the cafe car and the dining car also. The food is a little overpriced but not terribly. I got the mushroom pasta for dinner on the way out and it was delicious (cheapest item on the menu at $14.00) It came with a dinner roll, a small salad, and the pasta which was like big round raviolis filled with meat (five or six of them and they filled the plate) the sauce was good and I enjoyed it very much. There was a flatiron steak for about $23.00. Some kind of chicken dish and I don't remember what else.
Be aware the dining car is small and you will likely be seated with another traveler. I was actually seated with two others who were each traveling alone and we had a great conversation. It turned out to be fun. One was a lady probably in her 80's who was visiting grandchildren, the other was a young man in his 20's who had attended a friend's wedding. I'm 60 and on my way to visit relatives in Illinois and Indiana. You wouldn't have thought we would have had much in common, but we got along great and everyone had some great stories to tell!
