I've taken trips with Autobahn Adventures now for four years in a row, and I'm currently planning to take another trip with them as well. Everything is very well organized. Mark & Tina very social people and they work hard to make sure everyone's having a great time. They vary the trips each year as well. It's a wonderful experience, and the number of people that return year after year is amazing. I've made so many new friends over the years.
