Travel information

See this link for travel information. More information can be found here. International visitors should be aware that it is often significantly cheaper to fly into Dusseldorf (DUS) or Frankfurt (FRA) and take the train to Bonn, rather than to fly directly to Cologne/Bonn (CGN). Getting to Bonn from these airports by train is straightforward and does not require extensive knowledge of German. As the conference approaches, there will be a signup for participants who are arriving at similar times and would like to travel to Bonn together.
