Amanda,
Your best bet might be to travel from Munich to the C.T. via train. It's going to be a long journey, so you'll have to allow a full travel day in your Itinerary. It would help to know which of the five villages you plan to stay in, as the travel time might be slightly different depending on whether you access the C.T. via Genova or La Spezia.
One route to consider would be:
Dep. Munich 09:32, Arv. La Spezia 21:13, Time 11H41M, 1 change in Bologna, compulsory reservation. From La Spezia, use the small local train to whichever town you'll be staying in (check the schedules to make sure they'll still be operating at that time)
I looked at some of the night trains, but that wouldn't be my choice as these seem to have 3-5 changes - you wouldn't be getting much sleep!
Hope this helps? Happy travels!
