Approximate areas of new and old sites are given on my previous link.
If you include that some facilities may be on the field with the dance tent, the actual area for camping may be the same or larger than at Bulverton - and it promises to be much more user friendly (once you have got there).
There are a couple of very large and quite tempting fields immediately to the north east of the proposed new site: these might be a car park or overflow camping. They are flat too. And of course there are the alternative commercial sites nearby.
