I am going to be in Frankfurt with my kids (ages 12 and 13 ) in July for 3 days .
I am trying to create an itinerary which will include maybe one full day guided tour to Rothenburg and maybe 2 half days with a River cruise and day tours to maybe Heidelberg or Mainz . Plus sightseeing in Frankfurt ... I looked only at Viator guided tours . Any other suggestions? Thank you very much in advance!Edited: 10:55 pm, March 06, 2013
