On a MR to make 1K on UA. Arrive 6am Saturday Nov. 10, depart next day at noon. Suggestions on modest lodging, fun things to do on Saturday day and nite. Appreciate your time and thoughts.

I can't advise on lodging, as I've got friends, but for a day, go to the city center and wander around the Marienplatz area -- pedestrian zone, Frauenkirche, St. Peter's, Viktualien Markt, etc. Go to a cafe and have some coffee, wander around more...

If the weather isn't cooperative (or even if it is), there are a number of good museums. If you are into technology, the Deutsches Museum is first-rate. For art buffs, the Pinakotheken - Old, New, and Modern are fabulous. I have a soft spot for the Lenbachhaus, which has a great collection of turn of the century (19-20) and 2oth Century art. If you are into history, close to the Marienplatz is the Residenz -- the old royal residence, which is quite nice and also has the Schatzkammer or treasury with lots of valuable stuff that can be nice to look at. Nyphenburg Palace is another royal residence that isn't as central, but has a lovely park surrounding it and is still easily accessible from the city center -- the public transit system is great.

For the evening, maybe go to a beer hall and make some new friends or perhaps to go a concert if you like cultural stuff -- there is never any shortage of highbrow and lowbrow entertainment.

Enjoy -- Munich is one of my favorite cities in the world.

If you are science minded, the Deutsches Museum is a must-see. Take the S-bahn from the airport to Isartor and follow the signs. English language guidebooks are available in the vending machines.

Drink beer from the source at any number of sidewalk cafes and if you are looking for a cheap place to stay, the Mercure has several places that are quite cheap, including downtown right by Marienplatz and the Frauenkirche. The Hiltons are really nice but can be pricey.

MUC is my favorite city. Its too bad that the new train is not up and operational yet.

Which train? The transrapid? Be patient my friend, this will take another half decade or so...

At the Nationaltheater on Saturday night 10.11, the new poduction of Eugene Onegin by Tschaikovsky, conducted by GMD Kent Nagano and produced by the avant-garde Polish director Krzysztof Warlikowski, who always puts on an interesting show

Tickets are still available as low as €12,50 and can be purchased online:

And it's a lovely venue for a performance. I recommend the Rote Grueze (or something close to that - I'm blanking) as a nice intermission snack! ^

Many good suggestions already to fill 90 hours in Munich.
Too bad you did not hint on what interest you (sight vs arts). Should you take on the arts theme, museums are sort of spread out. A good couple of hours slow walk from the Residenz to the Alte Pinakothek. The Deutsches Museum is to the east side. A good way to traverse the city is via subway and trams (perhaps get a 1-day pass).
For most if not all visitors to Munich, Marienplatz becomes the natural focus point. Definitely hang out there for a while. Check out a couple of churches, cafes, beer halls (Augustinerbrau is right there) etc. I would go up to the observation deck of the Church of St Peter's where you will enjoy the panarama of Munich. Bring your camera (early morning and late afternoon are best times).
for more specific suggestions, give us some idea of what you are interested in.
