When I was 13 years old, I went on a school trip to the Forest of Dean.
The entire year came on the trip, and we all stayed in a wooden bunk house with 3 or 4 kids in each room. The teachers had their own quarters down the hallway.
We’d go on trips to nature reserves and railway stations during the day, and have lessons in the afternoon. In the evening, we’d all eat together in a tall hall with long wooden benches.
