Back in the early 1970s we backpacked around Israel, using public transport. We got talking to a couple who were there on a package tour. They had seen some sights as part of the package, but they asked us "How do you know where to go?" I really didn't know what to say!
These days, it's so much easier to look things up on the internet there really is no excuse.
Also back in the day, there were many American servicemen and their dependants (probably other nationalities too) who were flown to places all over the world, stayed in their barracks and on their bases and never had any contact with the outside world. I met many others, though, who were really interested and took their families to fun places every weekend. I live near several big American bases* and had some really good times with some of them.
YouTube is full of clips about (usually) American tourists who are"shocked" by even the slightest differences to what they are used to. They dont seem to get that the whole point of travelling is to see how others live, what they eat, and how they do things. And to learn from thjs. This is apparently a mindset that is not exclusively American.
* Gone now of course.
