My wife and are planning on arriving in Geneva on June 27th in the morning from Barcelona. The idea is to head to Gimmelwald for 3 nights, then go to Rothenburg for 2 nights, Salzburg for 2 nights, and then finish with 4 nights in Munich. Depart on July 8th. We're young and fit, and I know the trip from Gimmelwald to Rothenburg will be an all day deal, but I'm not sure where else we could/should go. Any thoughts?
