Are people coordinating on their travel arrangements? I will be at the weekend, and I'm currently considering a flight into Berlin-Tegel (from Norwich via Amsterdam) at 11:25am on the Friday, and a flight back on the Sunday evening. (This is by no means the cheapest way of getting there, but I prefer to throw money rather than time at a problem.)

The Google Map above is misleading: The event will be here, and easy to reach using public transport.
