We will be in Germany and Austria in April, staying multiple nights in both Munich and Salzburg.
We fly into Munich but stay in Salzburg first. I see the train station, both above ground and underground, is available right there in MUC airport. It looks like the above ground will take us right where we need.
My question is, do we buy train passes online in advance? Is it necessary? I would hate to waste money if we miss that particular train due to flight delays etc. Alternatively, would it be worthwhile to purchase a round trip train pass for when we travel back to Munich for our remaining stay? I noticed there is an underground train system that travels from the airport to the city center. I imagine that would be the best choice to get to our hotel. I guess I am just wondering if it is ok to buy train passes in advance or if we should just wait and get them day of.
Thanks for any guidance
