My husband and I are wanting to do a self drive trip through Europe. We fly into Frankfurt (June 2014) and wish to drive down through Germany (but which direction? Through Munich or straight down), through Switzerland, Italy (are there alternatives to the main road so that we don't travel over the same road twice, up and down?), Spain (through Barcelona to Pamplona for running with the bulls) then into France, drop the car off in Paris after 4 weeks. Any tips on this drive? We understand that we will spend time in the car, but we love to road trip and intend on spending multiple nights in some cities/towns.
