No Hannes, no day trip and doing almost exactly what you described.
My plan is 4 weeks, (one month) and somehow I also want to see the old churches in Prague.
Rome will also be a stop and France and I will pop into Austria to visit you and my friend Gustaf Schwarzenegger that also lives there, but he is not on Hive.
A camper van is definitely the best way to go.
Cheers and thanks!
