I take Amtrak for business trips NY to DC all the time. It's WAY easier and more comfortable than flying, and faster door to door too. Fingers crossed that the TSA doesn't start getting involved in passenger trains.
I have a trip to Chicago coming up, and now you guys have me thinking about going by sleeper car. It's cheaper yes, but I'm reimbursed for expenses so what matters to me is that it would be so much easier and would take about the same time, or even a bit less. LESS? Yes, since if you fly you have to start traveling about midday the day before, then stay in a hotel and have to finagle meals. With the train, you mosey down to the station in the afternoon and get fed as part of your ticket price. And, no boarding groups, gate checking, liquid & pocketknife ban, ever-shrinking seats, limited bathroom privileges, and standing in line for the creepy TSA treatment? What a concept!!! I'm amazed more people aren't doing this.
