Have fun.
I like trains. Am on them quite often, because of not owning a car. Haven't made that many long trips though, and only two trips where the cabin was changed into a sleeping cabin over night. Loved that, btw. Not sleeping, but the dark, and then listening to the sound of the train. Did miss the visual of the Alps and the tunnels there. But, since tunnels do scare me a bit, that was not too bad.
