There is a picnic area with seats by the car park before you enter the pay kiosk. You are not allowed to take food into Wisley. The picnic area has benches dotted about. We often eat there before we go in.There are routes suitable for disabled and they have a little motorised conveyance but you would have to ask about that as I do not know the details and when it is manned.Take your cameras 8)
