DDR Panel, Room Bonn.
Well, it was very bad for me, especially the first day (Wednesday).
I came to the room half an hour before the planned opening to set it up, but there was nothing of what I requested (No beamer, No screen, no sound), and the room wasn't prepared at all. So I decided to open the panel 1 hour later, and I asked the con ops if I could have all the stuff ready one hour later. One hour later, nothing, so I had to run everywhere to get the sound and the beamer, and I didn't get the beamer screen at all... I had to use a towel with duct tape to make a screen.
Finally the panel opened 2 hours later than planned.
It was okay the others day, though.
