I'm looking to go from PDX to CHI via CS and CZ in roomette end of October. What happens If I miss because of CS being late? What are the chances Amtrak would transfer my CZ reservation to the next day? Would I be subject to the change in price when changes made in the itinerary? I assume it might be a lot more which would be a deal breaker for me. I have a limited trip window so being safe and planning an Emeryville overnight is not a good option. I would appreciate any suggestions for this tight scheduling challenge. Thank you in advance.
