===== Directions & Dinner Location: =====
Please use following maps to find your way from {{:na:engineering:ew:airport_map.pdf|the airport }}\\ to the hotel and 
to find your way to {{:na:engineering:ew:chalmers.pdf| Chalmers University of Technology }}.\\
\\
//On the Chalmers map, you follow the black line towards "conference venue".
You enter the building where you see the text "Reception" (just close to Chalmersplatsen) - please  don´t mind about the black points on the map, because we were informed only today, that this entrance will be closed when we have the RadioNet conference!
Inside the building you will be shown to room "Scania" by reception desk staff - the room is situated straight ahead from "reception entrance", please pass the small café,  enter stairs to the next level, and there you will find "Scania".//\\
\\

The workshop dinner will be held on 23. June at 7.30 pm in {{:na:engineering:ew:city_map.pdf|Liseberg }}\\
We will meet us  at the hotel Panorama at 7 pm.\\
