What is the best way to travel from Munich to Prague. Leave Munich a.m. get to Prague (how long), stay overnight and travel back to Munich.
If you take the train it's at least a 7 hrs journey. For details have a look at

Probably with the limited time you seem to have, take the train. Check if there are any overnight trains (http://bahn.de).
I just took the train from Munich to Prague a week ago and it took us 6 hours. Based on my experience I would arrive in Prague during the day because getting in at night gave me the wrong impression of Prague. The train station is a little shady at night. Also, get to the train at least a half hour early. It was hard to find a seat at first but many people got off at the various stops. I think leaving Munich in the am sounds good to get to Prague!
