I went to this show the year before last and found that we were just asked to park up in the usual rows non dependant on car type.
It may have changed, but I found the field to be less than ideal for a Morgan being very lumpy and bumpy, we were also squashed in so that visitors were constantly walking through the gaps between the cars.
There are much better shows in E.Anglia such as Helmingham or Hevingham but of course it's all down to personal choice.
Here for a good time not a long time!!
