My only trip was in Junior school, to Colomendy School Camp, near Mold in North Wales. It was quite cheap, but my parents could ill-afford it. They scraped together a little spending money to last me for the week. When we arrived I was horrified to find that we were expected to pay for an outing. I was left with virtually nothing to spend, which was mortifying for a shy little girl like me. I didn't let on, and pretended that I didn't want to buy anything.
We lived in Nissan huts. Very basic. That was my first, and last, holiday until I took myself away at the age of 18.
