Went skiing for a weekend in February 2012, stayed at the excellent Hostel der Athleten which is right by the Olympic ski jump.
Snow conditions were perfect and despite being advised this was the busiest weekend of the year we did not find long waits at lifts or the slopes crowded. The queues there were very polite and orderly, and the lift systems 1st class, very impressed. Skiing area is not massive so a weekend was enough to ski all the 'Classic' area, we did not go up to the Zugspitze as the conditions closed in a bit on the 2nd day. The Kandahar run and the other runs down to the valley are superb and long if the snow is good all the way down (which it was when we were there). We hired ski's etc from the ski school at the bottom of the Hausberg lift, again very well organised. We ate at the Fraundorfer (trad Bavarian) and a Pizza place down the road in the Partenkirchen area (which was very pretty), Late nights there is only one place to go, Peaches in the Marianplatz area was great fun, check out their Mega Zombie cocktails if you are feeling brave and there is enough of you. Will defo be back as its only an hours drive from Munich, so can easily tag a weekend on the end of a work meeting.
