We are wanting to see King Ludwig's castles while also experiencing the beauty of the Bavarian Alps and the small towns that surround them. Reading Rick Steve's books, we are leaning toward traveling to Innsbruck from Salzburg (to see the town and Alps) and then to Fussen to experience the castles. From there, we would end our trip in Munich.
I am struggling in finding options to get from Innsbruck to Fussen without our own car, though. Some sites allude to buses taking the trip (i.e., 160x and 4258), but not all confirm it. I also am struggling to find out if this would be a bus trip that might be difficult for someone who gets car sick. Finally, I don't want us to travel all the way to Munich back down to Fussen...
Long story short, anyone been to one or both towns and have recommendations on whether to visit both and/or how you got to the two locations?
