I had no problem signing up for Guest Rewards about a year ago, so it must be some blip with their web site. With Amtrak on the Chicago to Ann Arbor line, about a third of the time I arrive within about 20 minutes of the scheduled arrival (on time), about half within an hour (pretty good), and the remainder an hour or more late. That's still better than the airlines. I took the Philadelphia to Chicago overnight a couple years ago and found it fine. On overnight trains the seats are more like LaZBoys, with a flip-up ottoman.
