So I have read that the Munich factory tour is not available from December 12-31 because the factory is shut down, but is the same true for the Dingolfing? We are doing an ED on the 21st of December and will be in the area from the 20th-27th. Are there any tour options during that time?

Can Rolf use his key to get us in after hours? I'm sure there isn't much security other than those furry German Shepherds and a bunch of Dachshunds...
