Directions for free parking for Susanne (but you'll be coming to the pub first, won't you?):

Follow the direction for Deliplein until the last set of traffic lights (at the Korreweg), where, instead of turning left, you go straight ahead.
At the next set of traffic lights (Bedumerweg), get in lane to go straight ahead, but instead take a left onto the 'service road' straight ahead (explanation: the road you're on, which is covered with tarmac, used to be a canal. On the sides are the old streets (stone). You want to take the old street on the right-hand side).
Take the first street to your right (Almastraat) and find a parking spot!

To walk to Willem's: go back to the main road (Bedumerweg), cross it. Behind the snackbar, take the Riouwstraat. Take the first street on your left (Bilitonstraat). After a few yards, you can turn right onto the Sabangplein (not a street, but a place/enclosure/Platz). On your left is an archway to the Deliplein. Inside the archway, it's number 116!
