I traveled around South America while working remotely a few years back. There's almost none of this disneyfication. In Ecuador, Peru, and Chile it was extremely normal to have days with no interactions with anyone who could speak English.

I know that this article is mostly about those who live in the host city, but it does also mention the experience of the traveler. For any travelers looking to avoid these situations, there are plenty of wonderful places to go where there's not disneyfication. I almost just began to list countries out but really: It's almost everywhere other than a few major cities in Europe!
