I'm also doing a MUC MR....well, sort of... and I appreciate all the suggestions in this thread.
I'll be there Dec 6-9 and scheduled the trip to pick up my new car at the factory. I should save enough on the car to pay for the trip, which is what makes it a MR, although if you factor in the car purchase, the cost/mile is way high!
If you are into cars, you may be interested in a visit to the
BMW Welt for a factory tour or just to check out the architecture. Quite the place.
Looking forward to Christmas markets (if it's snowy) or the autobahn (if it's not)!
