BTW I am the devillishly good looking one in the tatty black jumper and combats.
Tents are great fun except for slugs, but pellets soon sort them out. We sit around in our new (well new to us) portacabin drinking in the evenings, or sit round a bonfire with a can of fizzy pop or something. I suspect some volunteers only come back every year for the laugh! But we are serious during the day...
You have the right plan for your holiday, except there's not enough drinking!
Have a good time
