My wife and I are planning for Oktoberfest and this will be our first one. We want to make sure that we understand what choices we need to make when we register on March 1. Since my car is a Roadster, we will be using her car for the Driving School and would like to do 2 days each. If one of us registers with the Social Package, and one of us registers with the Ultimate Driver Package, which includes all four track days, would we be able to split those four days between the two of us, each doing two days? Or would we each have to register with a Motorsports Package and each add an additional Driving School a la carte? Since it appears that our registration may be tied to the vehicles in our Garage, how do I register with my Roadster but indicate I'm going to be using a different car for the Driving School? Or does that even matter?
