Im not sure, I was on a trip with my church and my youth minister took all the guys out there while the grisl did their thing. Im pretty sure its an open tour though. First they have a "lobby" aka showfloor and have some BADASS bmw race cars and such, then you go into one of those rooms where there is screens in a complete circle and its all one video and it gives you history and all that junk. Then they actually take you out on the floor, its insane! Id highly reccomend the trip if you are nearby.
