I am trying to plan a family vacation in June. My goal is to enjoy the clean beautiful air of the Swiss Alps, but also provide some fun for my teenaged daughter (age 18). So fly into ZRH direct from Boston. Travel to Lasanne by train (not car) or bus. Get a holiday flat in Lausanne for one week. Travel by train to various places in the Oberland and the Swizz Italian Alps. Also the French Alps maybe. What are your thoughts? Is doable? What are the flaws? Many thanks for your input.
