My wife and I are planning to ride the Crescent with two roomettes one direction and a bedroom the other direction. We each plan to take two bags, with everything being within the size limit of Amtrak's carry on policy. I can't remember if there is any extra baggage storage room on Viewliner sleepers (such as there is on Superliners on the lower level). Should we check some bags on either leg of the trip? How much can we comfortably stow in the rooms?
