Most folks going the full two day journey are in the sleeper cars. The Roomettes are Amtrak’s two person sleeper accommodations and they’re pretty nice (there are larger accommodations available, but the Roomettes are by far the cheapest and most common). There’s also meals included in the sleeper car price and the food on Amtrak is actually not too bad. If you’re traveling alone (or in any amount of people less than four) the dining car attendant will seat you with folks you don’t know, there’s tons to talk about. Lots of people, whether in the sleepers or in coach, bring books and have their tablets or laptops filled up with movies and series. My last trip up to DC I had saved a bunch of podcasts to listen to and finished Dan Simmons “Hyperion” series while I rode.
Rich assholes who believe they are smart as a side effect of being rich assholes.
