Dear Andi (and other organisers),
I realise that we have all only just returned from Berlin, but my thoughts are already turning to Vienna.
In order to help with my travel scheduling, can you please indicate if the meeting will run from midday on the Wednesday to midday on the Friday (that is, two full days spread over three calendar days)?
That would help me decide whether to get into Vienna the night before or come in on the morning of the Wednesday.
It would also be helpful to know the likely location so I can book a hotel early.
Sorry to be asking for stuff so early...
