I also posted this question on the Italy Forum (wasn't sure which Forum would be more appropriate).
I will travel Bolzano to Munich in September. I will purchase a German Rail Pass (5 flex days). The DB website tells that the Pass is valid on the EuroCity Train from Munich to Bolzano. I am travelling in the opposite direction. When I board the EC train in Bolzano, do I simply show my Pass?
I read that a seat reservation is required on international trains. How do I obtain a seat reservation? I tried on both DB and Trenitalia using dates in the next several weeks.
