We have 2 roomettes for our trip to LA from KC. We wanted them across from each other but they only had #2 and #5. We are traveling with our 2 teen daughters and are wondering how safe the train is at night?? From what we can tell our room is not as close to the other room as we would have liked. I have read that some of the doors dont lock???? There is no way I could sleep if the girls room didn't lock.
