... while you are in the area ...
If you find yourself with some extra time, why not hit some of the museums and sights in the area? First of all of course the German National Museum! Below please find the links to some interesting places.
Please note that many museums will be closed on Mondays, so if you plan to extend your stay, come a day or two early to the event. And do check the web sites of the museums you want to visit, their opening hours in November might be different from the summer hours.
