I took an Amtrak train from LA to Chicago in coach many years ago. I spent practically all of my time in the observation car, so it didn't really matter to me what my nominal seat looked like. I probably did stink by the end of the trip, but I was 17 at the time so it didn't bother me (at least I don't remember one way or the other).
I think there are two kinds of people in the world. One kind needs a sleeper for the trip to be enjoyable, the other couldn't care less. I used to be the second kind, but I don't think I am anymore.
I think I fall into the category of needing a sleeper to sleep. I wouldn't plan to stay in there during the day but there's no way I'd be able to fall asleep next to someone in the open like that.
I can't even sleep in a hotel unless there's a dead lock.
