I'm arriving to Frankfurt airport on Sunday, next June 23rd at 2pm. I plan to rent a car and drive down to Baden-Baden. I'm touring the Black Forest region and would like to get out of Frankfurt right away. My question - is the drive to Baden-Baden really only about 1.5 to 2 hours? I figure that by the time we get through customs and get our car, it will be around 4pm. I'm hoping we can arrive in Baden-Baden by 6pm or so - also, I'm hoping that traffic will be light since we will be driving on a Sunday. We are driving to the Hotel am Markt in Baden Baden.
