Traveling as a family

This is great! I advise to plan the trip in advance, what places you are going to visit. Plan the financial part of the program. Or if you are considering this option, you can just buy a program with travels in the EU and you will be driven and show you everything. But if that option does not suit you, then plan yourself. As for car rental, I can only advise a transfer from the airport, which I myself use when I travel somewhere. It's international, so there are in your countries, good prices, great drivers and I always liked the punctuality, click here for more information.
