Now as I begin to plan my 22 day driving trip, I have create a rough draft of my driving adventure. There are a few longer drives in this itinerary, but I'm from the Los Angeles area and driving is no problem.
(1 day) Arrive Copenhagen (CPH), rent, drive to the ferry at Nykobing, cross, and spend the night in Rostock,
Germany.
(2 days) Drive from Rostock to Berlin, spend the rest of that day and one more.
(2 days) Drive from Berlin to Dresden, spend the rest of that day and one more.
(1 day) Drive to Rothenburg ob der Talber, spend the rest of that day.
(2 days) Drive to Munich,spend the rest of that day and one more.
(2 days) Drive to Salzburg,spend the rest of that day and one more.
(2 days) Drive to Insbruck,spend the rest of that day and one more.
(2 days) Drive to Garmisch and Parenkirchen,spend the rest of that day and one more in that area and towns.
(1 day) Drive to Fussen, spend the rest of that day.
(1 day) Drive to Freiburg, spend the rest of that day.
(2 days) Drive to Heidelburg, spend the rest of that day and one more.
(2days) Drive to Koblenz, spend the rest of that day and one more.
(1 day) Long drive to Lubeck, spend the rest of that day.
(1 day) Drive to ferry, cross, and spend the rest of that day in Copenhagen.
Next day, return car and fly in the afternoon.
Any suggestions would help. I've been, for example, considering, skipping Fussen and Freiburg and going to Lucern, Switzerland for 2 days.
