My husband and I are first time Amtrak travelers going from Denver to Chicago, and then on to Cleveland, in a roomette at the end of July. I have noticed that the train often leaves Denver much later than the scheduled departure time. My question is, how early can passengers typically board the train once it arrives in Denver? We are very much looking forward to experiencing dinner on the train and worry that a delayed departure might prevent that. My thought is that if we can at least board the train during dinner hours, we can enjoy a meal while waiting to depart.
