Chris I'm currently looking at departing Sunday morning and putting in an extra eastern stop meeting up with you at Freudenstadt (Monday afternoon) to do the B500 through Baden Baden but going onto Boppard for our overnight stop Tuesday.
Then another two stops on our way home. (still to plan)
Sounds like a Grand Tour
We ought to book the hotel in Freudenstadt - any recommendations or just pick one off Booking.com?
