I have traveled to Germany many times and I am very comfortable driving there. However, it has usually been with a very small group or just by myself. In December, I am traveling with a group of 8, including me. We need to rent a vehicle that can accommodate us plus our bags. I have seen a few larger vehicles that can fit up to 9 people, but I am concerned about the bags. I am less interested in a two car option because none of the other travelers have ever driven in a country other than the U.S., particularly in winter. Any suggestions would be appreciated! Thanks!
