We will be visiting Switzerland with our 3 small kids (aged 3, 2, and 10mths). We would love to take in the views, walk some easy trails, be in the mountains, visit a petting zoo and experience small swiss village life... What city is better base to stay overnight in? Interlaken or Lucerne? We are thinking 2-3 nights and some day trips. We will have a car. Thanks in advance!
