Which is cities should I travel to and from (shortest travelling time) if I would like to visit Zurich, Lucern, Zermatt, Montreux and Interlaken in May? I'll be flying into and out of Zurich. The main places I would like to visit are Lucern, Zermatt and Interlaken. I would also like to visit Geneva, however, I do not think there're much "must see" in Geneva. Any useful advise would be appreciated!! Thanks.
