My experience living in the UK was that we’d go off as a family to visit Arundel Castle or one of the hundred other amazing things nearby, and the Brits I worked with would say “oh yeah, I went there on a school trip…” or “oh I’ve heard it’s nice.”
Denizens of a place don’t always appreciate what their location offers. That doesn’t make them cool or better than tourists.
That said, I agree that central London is not somewhere I desperately want to go every day. But there’s a lot of great stuff there.
I think I'm just jaded from trying to wade through waddling masses of tourists whenever I make the mistake of going anywhere remotely central on a Saturday or Sunday, but I get why if you're a tourist that stuff probably seems cool
