Is anyone else planning to go to Stuttgart that day to see the Mercedes Museum? (there is also a great museum and library in Stuttgart but the boat leaves at 4:30) We are in the process of hiring a driver -either round trip or possibly just from Karlsruhe to Stuttgart and then would take the train back. If you are going by train or have hired a driver I'd love to hear from you. We have one transportation company that we've had good success with. I imagine there are others out there.
