Decision time: because I'm all packed and ready to go, I'm going to go here
http://www.tomsfieldcamping.co.uk/index.html because I'm usually not able to because they don't take bookings and they usually get full very quickly on Bank Holidays.
I've rung them. They're open and almost empty at the mo. Grass pitches, some with EHU. They do have one area that's good for motorhomes but it's not big. Bongo type vehicles and cars should be fine.
I realise this is no good for many people (geography-wise) but it's too good an opportunity for me to try it. Also there's a band on at the Square Compass, Worth Matravers, that Gray is going to see and Gray and Brett will be on a posher, and more expensive campsite, not far from me.
You're welcome to join me if you're able to, but it's a first come first served campsite.
I'll try to re-arrange Eastnor another time.
