Hi Marco,
I just heeded the command and registered.
Great. Looking forward to meeting you after all those years.
I'd like to stay at the hotel, can you send me more info about the rooms you blocked?
Here is Edi's standard reply:
This is the room type of the quota

which they offer for 150 Euros per night if booked at least one month before the meeting. If you want one of those, use the keyword "Weitz120909". I think you'll have to call or email them, you probably can't use their online booking facility.
I was told they might still have cheaper rooms (other types) available as well. You should just ask them.
See you in Hamburg,
Arthur
