If your ever travel the Orient Express keep this in mind (it happened just over 25 years ago so may not be pertinent now) your luggage allowance is very clearly laid out and does not include a full size suitcase for your stateroom. Our neighbours did not adhere to these instructions, so teeny weeny cabin plus large suitcase (there was no way the steward could dispose of it and they didn’t have a smaller bag) the walls are very, very thin, I learnt some quite ripe language. Wonderful wonderful trip, DH spent a lot of time sorting out various passengers camera and of course then their film challenges so we seemed to spend some considerable time in the bar car, happy days.
Train travel is a little akin to river cruising - small cabins.
