I have been to Grainau every year for the last 6 years and the prices never change. There's never a price rise. We pay around 70 euros a night for 4 people and if you try and find a cheaper room so close to a major ski area you're going to have a problem. Grainau is a small sleepy village 5 mins up the road from Garmisch and it's only a train ride away from the Zugspitze, the highest mountain in Germany. The skiing up there is amazing with crisp snow and the feeling of a true French Alpine resort. But you better get used to T-bars as that's pretty much all there is up there. The classic area is much more German with tree lined slopes, loud Euro pop coming out of Garmisher Hause and the millions spent on the lifts cable cars and snow makeing has made it all the better. Access to Grainau is suprisingly easy with Munich being only an hour drive and with it being right on the edge of the Alps there aren't any mountain passes to deal with.
