"The on-site multi-storey car park is run by NCP and has capacity for 1,500 vehicles. Although there is a fee, there is an area on the ground floor - approximately 58 spaces - which is reserved for disabled customers, this is allocated on a first come first served basis. If you are unable to secure a place on the ground floor, there is a lift inside the car park that stops on levels 3, 5, 7 and 9."
