I'm working on our "Best of Europe" itinerary (mostly by train) and want to include Rothenburg ob der Tauber and the Night Watchman tour, as I've read so many good comments about it. We'll travel from Italy (Venice?) then perhaps to Salzburg then to Munich area. I definitely want to visit King Ludwig's Castles and then would like to include Rothenburg before departing from Frankfurt airport at 2:00 (14:00) on Oct 12. Should we plan to visit Rothenburg on the 11th and spend the night there? Will we have time to get to the airport? Or is there something along the way that would warrant moving Rothenburg to the 10th so we could explore on the 11th, staying the night closer to the airport?
