Let's say that I was going from Chicago to Atlanta via Washington and our train into Chicago was so late they couldn't hold or meet our connection. Or I was on a train into NY from the north and would miss my connection to a sleeper on the Crescent and Amtrak wanted to put me on the next day's train with no sleeper available.
Would they allow me to stay an extra night or two at my expense and take a sleeper on a train 2-3 days later at the same cost?
Would they, in the first case, allow me to route through NOL via the CONO and Crescent that same day with me paying for the NOL hotel if rooms were available without the overnight in Chicago and coach the next day? If the original route was via NOL, would they put me on the CL through WAS to the Crescent, again, if rooms were available?
If we had a bedroom and only roomettes were available on that replacement the next day, would they give us 2 roomettes in lieu of the bedroom we paid for?
In other words, how flexible are they to counter-offers without saying "You can do that but we will cancel and refund/credit the remainder of travel and you have to pay the full high-priced last minute prices?"
