I would go specifically to Gammertingen, Germany and spend time with my host family there, and visit Burg/Schloss Hohenzollern. Then I would go to the local grocery store and buy a crap ton of Ritter Sport and Mezzo Mix, and then share it with my family and friends.
Italy. For reasons other than the obvious xD. I've always wanted to go there, and my friends who have been there say it's really pretty. Plus I'm a quarter Italian.
