We are travelling form Zell am See, Austria heading to Koblenz, Germany and I have noticed a nice looking spot in Rorschach Switzerland that might be a good stop over. In particuliar a hotel named Minotel Weisses Rossli (any feed back?). The location on the lake looks amazing. Also, is it better to take the ferry over to Friedrichshafen and then drive over towards Frankfurt or enjoy the tour around the lake and cross at Konstanz? Thank you in advance.
