@Walter Hinteler,
For the most part they are all set. All the hotels and transportation between major cities is complete. The only thing not booked is a hotel somewhere in Germany and one in Switzerland.
I am just not sure where we will be to stay over. I am thinking Mannheim might be best in Germany, but I am not sure how long we will be in Kaiserslautern. In Switzerland I want to stay in Lauterbrunnen, but there might be more to do in Interlaken. So those are still in the air.
I just got the lease on a car last night. Had to fight about the one way drop off fee of 800 Euro's... Who knew that was a thing? But, 800 quickly becomes 200 when you get companies fighting for your business.
