When you arrive you will find that you have been allocated a changing room (probably 5 or 6).
As usual, parking is likely to be tight at Camberley so if full suggest that you advise your parents to park along Watchetts Drive (GU15 2PQ) and enter via the side gate to the ground or park in Wilton Road (GU15 2QT) on non-active factory unit parking and road and walk to the ground.
