Conference Program
The scientific program and included breaks will be held at the Congress House. A welcome drink will be offered on Sunday at the "Chalet du Telethon" which is located just behind the Hotel "Les Sources". All others meals will be held at the hotel Eurotel Victoria.These venues can be found on the map of Les Diablerets which is available on: http://www.diablerets.ch Since the "Chalet du Telethon" is not on the map, you should look at the Hotel "Les Sources" for finding it.
