We have 12-13 days on the ground in Switzerland. We like the trains, funiculars, good food and a bit of light hiking. I am in the planning stages right now. My thoughts were
Bern-3 nights (husband wants to visit Einstein museum and home)
Zermatt-3 nights
Murren-5 nights (as a base)
Zurich-1 night before flight home
Anything I am missing or should change?
