Hey, we did this exact trip in 2009. We were traveling with a two-year-old so we wanted to keep driving to a absolute minimum; no more than three to four hours a day. Here's what we did:
Day one: Munich to Baden-Baden. Stayed a hotel Merkur and really enjoyed the Black Forest.
Day two: Baden-Baden to Beaune, FR. Stayed at a nice hotel who's name escapes me now. (Will update if helpful.)
Day three: Beaune to Lyon. Stayed at the excellent (in every way) Villa Florentine.
Day four: Lyon to Avignon via Beaumes-de-Venise and Mt. Ventoux.
We went in late May and had perfect weather (except for two hours of rain driving from Munich to Baden-Baden). Good luck!!
Belgian Beer, Swiss Watches, French Bikes and German Cars. Life is good.
