I was checking out the prices for a trip from New York to the South... on the Silver Star or Meteor. The trains has roomettes for two people... I noticed that it has an in-room toilet out in the open. I've no experience with this.... does it smell? Seems kind of odd to have a toilet right there... When one person uses it, should the other one leave the room? If it's a #2, won't it stink up the room for a good while? Also, how does someone get to the top bunk in the roomette? Any advice appreciated!
