First off, no where does this specify the length of drive. You go about 2.5 hours to Rothensburg (get food for lunch - you get two slices of bread with a slice of cheese and water). From there its about another 3 hours to Austria. We hit a lot of traffic so we missed the planned tour and did a later one which allowed us some time in the city for dinner before a castle tour from 5:15-5:45 PM and then we had to quickly scurry down the mountain to catch the 630 PM bus ride back. We returned to Frankfurt around 1130 PM with no stops along the way. It's a very long day - I brought my airport neck roll. However, drivers were very informative Roolph happily spoke with passengers and told us history along the route. You wander Rothensburg by yourself for 45-60 minutes (not much time). By the castle they give instructions and offered if you wanted to hike mountain to the caste (40 min walk) that you could walk up with driver or take a horse carriage or bus. We opted for the bus up and walked back down. The castle was gorgeous outside, but there was a lot of preservation work going on so a lot of scaffolding and drapes covered materials. I had not realized before going that the castle was never completed before King Ludwig's death so it's not a very extensive tour.
