But I'm wondering how they handle a light AC arriving (just flying in
but not specifically for the show) prior to the field being closed for
the actual performance. Seems like it would be difficult to collect
the admission since when you land, you are already behind the fence.

Well, my take on this is that pilots are a step above most, in class and
honesty. Paying is something they do because it is the right thing to do.
