Myself (50), wife (45) and son (21) are planning for a one week trip in May 2012 as follows:
20/05 Fly in to Munich and rent a car.
20/05 to 25/05 Munich - Stuttgart - Berlin by car
26/05 to 27/05 Prague by car
28/05 Vienna - return car and join our friends for another trip
Does the above make sense - and any general tips for this trip?
