Thanks....I think we'll just barge into the dining car out of EMY, assuming the train is on time, and mark any old sleeper room on the check....then worry about catching up with the conductor when he/she gets to us. Clearly there are plenty of roomettes available on the train, priced in the lowest bucket. Unfortunately we can't buy one ahead of time, because we're using a companion coupon.
There are a couple of problems with this:
1. Not all conductors are willing to do upgrades. Even if they are, they will generally lift tickets for everyone getting on that stop before they will come back and do an upgrade, and EMY is a busy stop. At EMY, my guess is they would not want to be bothered with doing an upgrade until after they lifted all tickets at both EMY and OKJ, since the stops are close together, and they'll have work to do "on the ground" at both stops.
2. You shouldn't move out of your seat until your ticket is lifted.
3. If you do go the diner, and have your ticket lifted there, you are almost immediately caught.
4. The sleeping car passengers that have been on before EMY were likely on the train the previous day. If you make up a room, you might be picking one that is actually occupied and that the crew has already served. A lot of crews are pretty aware of who belongs where. And if they are suspicious but unsure, it is really easy for them to check the manifest. The LSA is responsible for seeing that the passengers in each room only get the meals allotted.
5. If you get caught falsifying a sleeper meal check, the LSA and the conductor will be really PO'd, regardless of your intention to do an upgrade (which in all honesty, you cannot know if one is available). I can almost guarantee you that you will not only NOT get the upgrade, but will likely be removed from the train at the next stop. It is possible that removal will be into the arms of the police for "theft of services"
That is a really, really bad idea. If you aren't confirmed in the room before you walk into the diner, buy your own breakfast.
