People tend to check in during these times:
Bring your parka and mittens cuz it's friggin freezing on this train.
Train was a cool experience besides being an hour late...
Gotta pee? Better ask for the key quickly
Doesn't open till 6am
Seat by the door, first dibs on seats and the elevator.
Watch out for Amtrak delays. They rarely seem to operate on time.
Station hours are 6am to 1am. Don't get here too early...
