We just got back from over there in January.

Munich is a MUST. And make sure you go to the Hofbrau Haus. We didnt spend nearly enough time in Munich, but Germany itself is just amazing; we could have spent weeks there. I wasnt a fan of Paris at all but I did the touristy things. Driving in Paris is definitely an experience but the autobahns are fine. We went to Amsterdam but I wasnt impressed (could have been due to NYE holiday). The outer towns in the Netherlands would be amazing I think, we just passed through but I saw so many places I wished we could stop and explore.
