Hoping to drive to Italy next year and would like to stop in Switzerland for a few days. Everywhere looks amazing! Any recommendations? Kids will be 13 and 7. They like campsites with slides, playgrounds and ice creams. We like good public transport and a town to walk to, ideally lakeside or views and some good things we can do without having to move the campervan. Lucerne? Lausanne? Interlaken? Thanks all
