The 18th Dutch Testing Day will be held on November 27 2012 in the conference centre Het Vechthuis. It is situated along the Vecht river (so there is no fighting going on here, although the name could suggest it to Dutch speakers).
The address is: Jagerskade 13-15, 3552 TL, Utrecht, 030-261 3543
The Vechthuis is easy to reach by private transportation and has plenty of parking space. Parking on the grounds is free of charge. Detailed directions, in Dutch, can be found here.
Public transportation to the Vechthuis is excellent. The busses 6, 26 and 36 will take you from Utrecht Central Station to the stop at Anton Geesinkstraat in 10 minutes. From there, cross the metal bridge and take a left turn and you will find the entrance to the Vechthuis on your right after 150 meters.
