I went there several years back.
I had a lot of fun, I don't know if the venue is still the same but they had a fairly large hall with an upstairs that had rooms for changing clothes/nappies, and a decent outdoor space that was sheltered enough that yo can't really see in.
The host (ms Livingstone) and staff team were very welcoming and friendly and explained their rules at the start and were especially helpful toward new attendees (like myself). There were many tables around the hall with various activities on them as well as floor space for things like Large grubbt bricks, book corner, soft play etc.
The garden had activities too and they had a fair sized "paddling pool" (it was summer) as well as water pistols and all sorts.
They stopped halfway through for a snack time and had little lunches for people and there was milk and juice available. The main organiser and some of the staff were willing to change peoples nappies but there was a strict no messing rule, they also have a no impact rule (spanking) even if attending with your caregiver in order to not upset anyone.
They finished off with a little story time and then asked anyone who could for help to tidy and pack away.
There was a good 120+ people there that afternoon possibly a lot more my memory is not great some in full abdl clothes some not and some in between, caregivers were welcome and everyone I met was very friendly.
They also hosted other "themed" events for things like halloween, but they are a regular (I think it's every 2 months, might be monthly now) and possibly one of the UK's biggest event and well worth going to if you are more AB or little than DL.
I would happily go again but have difficulty getting there as I don't drive and it's awkward to get to from Bristol without a car.
The organiser began the NGM as a fetish school role play event for people into that and I do believe corporal punishment is a thing at that one, they branched out into Pre Prep many years ago.
