We are travelling in mid-October for 5 days. A large group with 3 children. Our main objective is taking in sights and the Swiss experience - not into hiking. We will be doing a couple of train journeys also, to Lucerne etc. Would be doing Jungfrau and maybe one more mountain excursion during our stay. We intend to stay in self-catering apartments.
Should we make Interlaken as our base or Grindelwald?
