I should be able to get on a bullet train from SF in the morning and get to NY the next morning. In a comfortable six seater/couchette, I should have myself a great day meeting people, chatting, reading a book, then have a great 8-hour sleep, and then arrive in New York fresh and rested.
I fly to NY fairly often and although the flight is six hours -- by the time I get to the airport, wait at the airport, board the plane, wait for takoff, land, get off the plane, get baggage, and get from the airport to the hote -- i have spent twelve hours travelling and it has all been EXCRUCIATING. And when I get to NY I am exhausted and irritated. Right now I pay 350 round trip on Jet Blue. But I would pay double that to do it comfortably on a train.
