My wife and I will have a near 12 hour layover (9:55-21:55) in MUC on September 18th on the way to BKK. Can I assume that the permanent beer gardens (ie. Hoffbrauhaus) will still be open as usual? Other than crowds, is there any attractions I should expect will (or will not) be open due to Oktoberfest beginning later in the week?
