Take the train to the Congress
As in previous years, the German railway company (Deutsche Bahn) is offering a special ticket for your travel to the Congress. But opposed to the last years, the cheapest fare has been changed from 89,00 to 99,00 Euro – there is no more discount for booking the ticket online.
All further information regarding this special offer and how to book it can be found in the Wiki.
Furthermore, an extensive list of hotels and other accommodations can also be found in the wiki: Some hotels like the Generator Hostel and the A&O-Hostel even offer a special rate for stays during the congress.
