If you haven't booked your hotel yet, and you want to stay at the
conference hotel, think about doing it soon. We've asked for an
extension twice, but these have expired and the group rate is ending
today (unless they give us another extension - which we'll ask for).
If you don't get into the conference hotel, there are other options of
course (check the wiki) but, if you want to be there and haven't
registered your room yet, now is the time!
