If you’re in Germany, don’t go to the fest in Munich, as it is just too big and too crowded to have fun. Go to another city, like Stuttgart, where the festival is still large, but not so gigantic.
The very best are smaller towns that hold their own fests, usually with their own brand of locally brewed beer. They have a much better selection of food, and are in it less as a money making exercise than to just have a good time.
Among the towering achievements of Western Civilization, the above is very much worth fighting for.
Just to have a good time--the West invented that.
