Hello--arriving into Zurich the 1st week of March. Have 4 nights =3 full days. Where should we go---2 adults and college son.
Since you don’t have time to visit the Lauterbrunnen Valley go to Zermatt instead. From Zürich Flughafen (airport train station) take a train to Zermatt that requires a connection (3h 30): https://www.sbb.ch/en/timetable.html.
