We usually book a bedroom for our travel that involves an overnight, but this time we are only going to be on the Coast Starlight for approx. 12 hours, so we booked a roomette so that we can still enjoy the atmosphere we have become accustomed to. Is there a way to lock your roomette doors when you are away from the room and enjoying a meal or the lounge car? If not, is there much plifering in the sleeper cars? I assume I can shade off the windows when we close our doors and walk away? Thanks for your knowledgeable assistance.
