I and my brother were lucky in that my dad was a headmaster and we (together with mum) got to go on holiday with him to Colomendy, N Wales, to a camp site which catered for overseas and home schoolchildren of varying ages.
They were housed in wooden chalet dorms but each teacher had a separate family room at the front of each building. It was an exciting two weeks with long 'leat' walks and trips to an old-fashioned tuck shop, mushroom gathering at 5am (supervised) and evening songs round a campfire after supper, with a group of German older teens and their tutors.
We ate with my parents in the formal dining room (all starched cloths and napkins) but would have preferred to eat with the other children.
I can even remember cheeky Bobby Thomas who grew up to own a fruit importing company and sent my parents a crate of fruit every Christmas.
Great days.
We also rented holiday cottages in Betwys, Farndon and on Deeside where we messed about in boats and went for milk, butter and eggs to local farms. Those were the days...
