Visitors to Munich WILL get frustrated
if they want to buy a ticket at the main station. Long queues,
waiting for a long time. You must draw a number and wait, sometimes
there are 50 people in front of you. The ticket machines are no
alternative...too complicated, sometimes even for Germans.
But to ease life a bit if you have to
buy a Bayern ticket or any ticket, do not go the Main station.
the Ostbahnhof, queues are shorter, few tourists and they sell
everything the same way.
