We are traveling with our daughters, 13 and 11, to Europe at the end of June 2014. We are starting in Paris and will rent a car upon our departure from the city. We are meeting family in Koln a few days later and then on to Leipzig. The question is which route to take - head to Belguim for 3-4 days or to Saarland/Rheinland region. I am wanting to find a base and take day trips. We prefer small towns/villages. We love great food and wine. I want my children to get a feel for the area and the flavor of each stop. I would like to spend 1/2 the day touring and 1/2 the day playing. Any advice is greatly appreciated.
