For people that use trains in Europe often, including night trains to sleep... let me know your insight, advice, experience, and recommendations. Looking to do Vienna in Austria, Neuschwanstein in Germany, and Interlaken and Lugano in Switzerland. Looking to be in each place 1- 2 days. Hope to do this without a car. If rail trains don't work how is flying to from and between these places? Also, hoping but doubting I can fit in Lake Bled in Slovenia (perhaps swap Lugano for Lake Bled). Looking to do this trip 6-8 days. I Hope night trains make most of this possible. Also, any other places you might recommend instead in Switzerland? I am not interested in Zurich except for flying in and out of Zurich airport.
