In my opinion, different kinds of travel inspire different things. Back in the day, travel necessarily meant mixing a lot with the people and culture you were visiting. Nowadays it's much easier to travel in a "bubble" with much more limited contact to locals and culture, besides those trying to take advantage of the tourists

A lot of rich people like to feel like they’re getting an ‘authentic’ experience on vacation so they visit remote villages and hire locals (who are usually well versed in entertaining rich tourists) to give them ‘authentic’ tours and taste the local booze. I doubt this is what Twain was talking about though.
