My husband and I will be traveling from Venice to Murren staying for 4 days and then on to Paris. We have made the decision to purchase a 3 country eurail pass. I have 3 questions: 1) is Interlaken the best station to arrive into Switzerland and then how do we purchase the tickets we will need to get to Murren? 2) which station in Interlaken would be best to arrive, east or west? 3) Are there ATM machines in the Interlaken station so that we may purchase Swiss Francs when we arrive?
