"The park was once a Council waste tip until reclaimed in the late 1950?s! It is now a large (45 acres) open space offering a range of sports and leisure facilities around an 8 acre boating lake. The site also has a miniature railway, childrens playground, café, nine hole Par 3 golf course, putting green, go-kart track together with some landscaped areas that provide year round interest for all ages."
I'm going to be controversial and say that I would absolutely love to go there for the day. And I'm on the autism spectrum and a mum in her 40s. One of the best days out I've had in years was with another friend on the autism spectrum and her young lad (also ASC) at Legoland. We played, we marvelled, we ran about.
There is sometimes a concept that people on the autism spectrum want to be mature, sophisticated, adult, sensible. And that anything that is childlike is patronising.
I'd say that a good few of us don't want to be replicas of neurotypical people, and a good few of us don't think that kind of activity is too young for us. But we're sometimes so worried about 'fitting in' socially that we pretend to enjoy (say) sophisticated parties where everyone bitches about each others' clothes or lifestyles and we end up feeling utterly alone and excluded and unable to join in and scared witless.
A day at a playground? Wheeeeee!!!!!!
Obviously, the individual views and opinions of the person in question should be asked, using whatever communication methods they use.
