Good travel blogs maintained by locals are immensely valuable. They usually have much better technical advice about local culture, airports, payment, SIM cards and that sort of thing.
I just stayed at an Airbnb in Crown Heights (Brooklyn) a week ago, and knowing nothing about the neighborhood but wanting to eat a meal there, found that Google Maps was a little overwhelming.

AI content feels a lot like the copywritten content it replaces: a shallow repetition of what an actual expert wrote down.
