I'd appreciate any insights and guidance on booking a trip on the Empire Builder from Jackson, MI to GNP. Plan to stop in East Glacier for about 5-7 days and then get back on westbound train to SEA and continue trip to AK. Thinking a roomette since this is just one person. How small is the room? Cozy? Noisy? How close are the bathrooms and showers? Do rooms lock when you leave them? Is there a table in the room during the day when the beds are folded up? Any other things I might want to know? TYIA
