We arrive in FRA on Sept 17 and fly out of HHN on Sept 19.
How do I get between the 2? If I understand correctly it's not to far and generally it's by bus. I'm wondering if renting a car would be good and then we can have some extra freedom to maybe see some castles on the 18th. It's frustrating me that I don't know what the heck I'm doing. Thank you for any help.
