Wherever it is, it is worth bearing in mind that practically all of the suggested dates are in the school summer holidays and prices and availability will be affected by this.
There are a number of members in the southwest who would find access to places like The Lake District or the southeast / East Anglia challenging. Within reason, we are happy to travel but it is the same distance north as it is south. I think north Devon is a pig to get to because you spend so long off the motorway to get anywhere. South Devon is a lot easier as it's only just over an hour from Bristol maybe 90 minutes towing a van. if that's still too far, how about somewhere like Brean or Burnham on Sea which is not bad for families and bigger sites have club houses with entertainment etc.
Sorry if I have opened things up again but there appears to be some concern over the already proposed venues.
My own view is that Devon is too far for a big meet - simply many would not be prepared to travel that far for a weekend. Therefore, you would not get too many people who would/could make it, even from midlands area. Obviously, the reverse is true, hence we didn't expect too many at the England v Scotland (Lakes) from way south. We have to use locations, I reckon, that as many people as possible can make it.
I suspect most are prepared to drive for up to 2 - 3 hrs, which is always going to make it diificult for the Cornish, Kent, East Anglian, West Wales, and North Scotland members.
Around Bristol should include all the West Country folks, Midlands Mob, Welsh, Bournemouth etc, London, etc. Obviously Bristol isn't necessarily the most picturesque location, but the Wye Valley isn't too far unless right in the depths of Western Cornwall.
The Western Devon location is going to cover all of Cornwall, Devon, Somerset etc, but possibly not much further :-/
What do others think?
