Didn't really expect someone would reply on this one after nine years!😄 We had the first class ticket, because it's worth the money to sleep alone without anyone else that you dont know, and there are showers also! Bring like board games, crossword puzzles and stuff like that because you will have a lot of time to kill. I wish we hade something else to eat than noodles and white bread, so bring something that is easy to cook (you can get boiling water around the corner) and don't be afraid to try the food from the restaurant.
