I am doing preliminary research on my next European vacation with my family (wife, 4 year old and 16-month old). We would travel in June, and we are considering a trip to Switzerland and / or Austria. We prefer to travel the country or countries by train, and we prefer three to four bases to spend the night. With an eight or nine night trip, do you recommend traveling to one or both countries? In Austria, we would definitely want to spend time in Vienna and Salzburg. In Switzerland, we would love to visit Lucerne, Zermatt, Grindelwald, etc. (day trips) if possible. If traveling to both countries is realistic, we would fly into Vienna and out of Zurich. We enjoy scenery, food, and any kid friendly activities.
Thanks in advance!
