This ended up being an extremely wonderful tour, and our guide Thomas was phenomenal. He provided a treasure trove of little facts and information regarding Frankfurt and the surrounding areas, as well as at our three stops. He was happy to answer additional questions, and work around our schedule when we requested some additional time in the Black Forest. We absolutely loved Heidelberg and the Black Forest, although we decided we could have done without Baden-Baden (it was an adorable town, but we thought it would be a better stop if you intended on spending some time shopping). Regardless, we would most definitely recommend this tour.
