Bathrooms are a HUGE plus when traveling by train. No “seatbelt signs are still on” restrictions - you can go potty whenever you want to!
And thank heaven we were on a train the last time I had food poisoning. It’s about a 4-5 hour drive from New York to DC; if I’d gotten sick during the drive, I might never have been able to leave the bathroom at whatever crummy rest stop we wound up at. Bleh.
The NY-to-DC route is one where the train is actually faster than driving nonstop would be, actually, vs others I’ve taken (e.g. here to Chicago is 12-14 hours nonstop, while the train is 18+ hours). The Empire Builder’s route from Chicago to Seattle takes 46ish hours and could nominally be driven in 30 - but assuming you do not have access to large quantities of amphetamines, it’s gonna take at least 1 night on the road, and thus would take as long as the train.
Amtrak, some years back, had a train from DC to NY that actually included sleeper service. I don’t recall whether it was part of a longer train - I don’t think so. But basically you’d get in at, say, 3 AM but you didn’t have to leave the room until 7 or something like that. I expect there just wasn’t enough demand for it.
We’ve booked the last leg of our big trip for next year. So, 3 days from here to Portland, OR; a few days there, a few days driving south to Los Angeles to visit family, a day back north to San Francisco, then 3 days from SF (well, Emeryville) to here.
My husband transferred the balance of his rewards points to me (fee of 20 bucks, cheaper than purchasing the same amount), and I did still have to buy some points, but even so we paid about half the retail cost for that leg (the Coast Starlight). We booked a roomette despite it being a 12 hour trip with no overnight, since we don’t know what COVID will be doing and we want the privacy. There’s always the sightseeing car if we’re on the “wrong” side. Plus it means we get meals.
I semi-jokingly suggested that for the night in Emeryville, we skip a hotel room and just hang around the train station all night, but I expect we’d get chased out as vagrants. There’s at least one hotel nearby, so we’ll likely do that.
