due to the length of the trip it’s not practical with non-sleeping seat
I don't know what this anti-train propaganda is going on in this post, but this is laughable. All of the seats are sleepers on Amtrak at least. I went from Cincinnati to San Diego without a sleeper.
Different people have different standards. I've done many sleeper trips and several coach trips across the country over the years. Coach was fine when I was a teenager, now that I'm approaching 40, I'll pass.
