Go Camping & Geocaching between Piratemania 11 and UK Mega 2018

This is only an initial meetup at this stage to gauge interest but I really enjoyed Piratemania 10 and had the idea of camping in Yorkshire between Piratemania 11 and the UK MEGA 2018 (there will be separate Meetups for these).
I assume Piratemania 11 will be somewhere near the UK Mega.

An initial look suggests the campsite at Ripon http://www.ukcampsite.co.uk/sites/details.asp?revid=3038#maphere might be suitable?
