Best places to park are:

(1) The "De Loodsen", or the "Piet Hein" Parking garage,
3,= per hour at about 600 meters from the venue.

(2) The "Oostenburgereiland" parkinglot for 15,= all night, about 950 meters walk from the venue.

(3) In the neighborhood for 2,50 an hour till midnight, free after midnight.
But it is realy difficult to find a free parking spot. Most are for local permit holders.
