Hello! We are considering taking an Amtrak trip next spring, and I am looking for advice. We have done short trips to OKC several times, but this will be the first long trip. We will probably get a roomette. Is the upper bed comfortable and easy to access? We are in our 50s, active but with aging knees! How do meals work on a long trip like this? The Heartland Flyer just has snacks, not a real dining room. Are showers available? Does this trip have any National Park Service talks? We have enjoyed these on the Heartland Flyer. On the schedule, several of the stops are longer. Are there interesting train stations to see? We will probably go to the observation car as you can only see one side from a roomette. Where are the most interesting sites? Thanks in advance for any tips!
