We will be in Munich for a short visit in June.
We have three full days and are using one for a day trip to Salzburg. We plan to visit Dachau as well. (Yes, I know this is a lot to fit in) We will need to get from the airport to hotel on the first morning and to the main train station on the fourth morning.
What's the most economic way to use the public transportation system? Daily passes? Multi day passes? We are staying at a hotel near Rosenheimer Platz.
