Just thinking out loud for a moment:
I'm situated directly at the Dutch & Belgian border in Germany.
By car it is an 1,5 hours drive to Crisis. By train the journey takes 2,5 hours, but we still have a belgian Rail Pass at home which allows a single ride (to any destination in Belgium) for 7,60 € only (per person).
Someone interested in a shared train journey?
Meeting point would be Aachen Hauptbahnhof around 8:00 o'clock in the morning. Dutch or Belgian fellows could hop on the train at several stations.
I imagine a train ride could be much more relaxed & communicative for everybody involved than a car trip.
