One note of warning : there is a lot of traffic at this time on Friday going towards Dingolfing. So don't rely on Nav system estimate, or ability to drive autobahn speeds.
I booked the tour for 9/21 and missed it by 30mons due to traffic. And when you show up late the entire welcome desk is unmanned so you can't see anything.
