Hello- My husband and I have a layover in Munich, arriving at 12:30 with our next flight takes off at 9:50.

How big is the airport and are customs cumbersome?

What is the bet way to get in and out of the city from the airport fast or is there a subway and is it faster? Should we hire a driver to take us around or are the sites central and walkable? We would like to maximize our time in Munich, walk around the city, shop and eat.

Thanks!
