I just reserved two beds in the City Backpacker for Martin Kiefel
(mrtrac) and myself. Is there another group up to 4 of attendees who
would like to share a room?

I am looking for a place for 3 (Atze Dijkstra, Jeroen Fokker, and me) for Friday and Saturday nights. I don't think the others would mind sharing a room.

If so, I would send a mail to the hostel,
asking if that is possible.

Let me know if you want to do this; otherwise, I'll probably reserve something tomorrow.

Regards,
Sean
