I don't think they do visit for the Let's Move To articles - I used to read the Guardian back when paying for "news"papers was a thing and I always understood this small, throwaway article to be a crowd-sourced and internet-sourced thing. It's not meant to be an in-depth review, just a light-touch look at somewhere. I suspect it takes all of half an hour to pull together, and shouldn't be taken as particularly important, accurate or useful, really.
