Surely the main entrance = the main gates.
In this case that is the ideal place as you get the traffic from both directions. And in fact I thought there was only really one way in, the way directly into the main car park (if you turned left a few yards after the gates) otherwise you would get down to the castle.
The protestors were directly opposite the main entrance to the St Hill estate.
The majority of cars parked in the field next to this entrance, and the entrance to this field was about 100 yards down the road (towards EG and away from the protestors). But even so, a large number of the arriving public went past the protestors as a lot of taxis and most of the coaches went either into the main entrance or into the rugby club car park further down the road in the opposite direction.
