Amazing, indeed! I came with a big group of people (18 including myself) and we tried almost everything - night activities (the Berlin's night life is amazing by the way), day activities (Trabi Safari was excellent, and my friends liked paintball). German food? Oh my good, very tasty. I just want to know where you get these ideas from? Excellent job! Keep it up!
We helped to maximize the fun during the trip in April 2011 for Luke and his friends. They had great time in Berlin.
