The only types of vacations you can imagine are visiting historic urban cores, going on a cruise, or going to a resort?

What about a camping trip? Or a beach trip? Or visiting family that lives far away?

I don’t think that wanting to experience other cultures is a consumerist behavior.

Agreed. People claim flying halfway across the planet exposes them to “different cultures” , but then do the most homegenized, Westernized touristy activities. I can learn more about a country and it’s culture in a single day via Wikipedia and documentaries than most tourists will gain on their “vacation” in same country.
