I can sleep almost anywhere, so I probably will sleep for a large part of the trip. We're going coach but I'm told train coach is like airplane first class. Wider seats, more leg room. They also have electric outlets so we can watch movies on my laptop. Kelli, my wife, is pregnant so hopefully it won't be too rough on her.
They offer first class with beds, but that's a lot more expensive. We'll see how the trip down is and decide if we want to upgrade for the ride back.
