Parking for 2000 cars at rear of centre,go down the slip road at the side.You collect a ticket from an automatic machine,and so long as you shop,eat or buy something or go cinema,you must ask that place to stamp the ticket.
On exit you insert the ticket into the auto machine and the barrier opens up.So it is free for users of the centre via stamped entrance ticket.
Look out for the gorgeous girl selling chocolates in the walkway upstairs
