Excellent - thanks so much for taking the time to provide all that detail. I had looked on the Amtrak site, and none of the information about changing reservations mentioned adding a passenger. Likewise for the Ask Julie tool. Tried calling a couple times today but got a busy signal.
Your help and advice is much appreciated.
