I'm doing a not-quite-so-pure run at the end of May. I will be there from noon Sunday until 5 pm Monday, so I have a bit more time. Staying at the Rennaissance Munich.

Is the Virktualienmarkt better done in the morning, for breakfast, or in the late afternoon on the day I get there? Should I combine it with sightseeing at the Marienplatz? What kind of timing am I likely to endure getting from the airport to the Rennaissance via subway, and how much time does it take to get from the Rennaissance to the Marienplatz?

What recommendations are there for "must sees" and places to eat? Is Munich a late-night town, or does it go to sleep early? If you had about 30 hours in town, what would you do during that time?

Any help you might give to this newcomer to Germany would be appreciated.
