Been thinking about this
One thing I would do is use the RFC carpark for extra food vans & tiolets
Club organise (yes pay for) an area with the MCC Car Park people for a set area for RFC staff, players & officials - say 200 cars.
By freeing up the car park you can get more amenities for the public and then move some of the queues to outside the main ground = creates more space
Just a thought
