I will be in Frankfurt for a business trip in mid-August, and I have one day (a Monday) free to explore. I travelled to Frankfurt last year and spent a few days exploring the lovely city. I've also explored the Rhine via different stops on a train during the winter, so I've seen a few castles.
I'm looking for recommendations for seeing the Rhine via one of the boat tours, as well as any wineries I could visit for a tasting that day.
I only have this one full day, so want to make the best of it.
Thank you for your suggestions
Suzette
