i suggest a make-your-own wine tasting event in the F area plus some shopping in the airport. you will need close one hour into munich and the same back, and if you include some extra time for safetey then there wont be much left.
If arriving in F, they will give you, on request, a dayroom at the Kempinski. Worth taking this, as it is a VERY nice hotel actually in the airport, with a good health club/swimming pool etc.
if you want to do that you got to call the kempinski in advance, its all really easy though. they just make a copy of your F boarding pass at the hotel. the hotel itself is actually pretty nice, spent a couple of hours there recently...
light travels faster than sound. this is why some people appear bright until you hear them speak...
The city is 45 minutes by train (one-way) so it doesn't make sense at all....
i wouldn't say "no sense at all".
sounds like the OP has never been to Munich, so take 1.5hrs time on the train, 1.5hrs back at Airport before next flight (to play it VERY safe and have time to shop/ F lounge wine tasting) and he still has 3hrs downtown...
plenty of time to stroll around, get a first impression and so on.
(most tours ala "Europe in 7days" prolly spend less time in Munich, I reckon ).
I'd take the train (~10e RT with a daypass), Taxis are ~120e RT
all depends on what the OP is lookin for, of course. all other options are also good, thanks for bringing them up...
wolvie007 PM me if you need detailed info or wanna meet up for a drink
To Kloster Andechs, home of the world's best beer, have the cab wait while you drink 5-6 litres
Kloster Andechs is nice but that is really far away from the MUC airport. It's at the Ammersee which means it's about 75 kilometers away.
In the little timeframe the OP has I would rather go to downtown than making all the way to Andechs.
I would take a typical bavarian meal at the Franziskaner for example and then walk around a little bit in this nice area where also the Franziskaner, a lot of shops and attracions are located.
