Do you just have bad reading comprehension, or are you being disingenuous?
Obviously there's Disney parks in other countries. I said as much above. But while there's also shittons of other parks both in and out of the US, why do you think you specifically chose to use:
some poor sod who’s been saving up for a decade to take his kids to disney most like
as an example for why people would travel to the US? Is it because
some poor sod who’s been saving up for a decade to take his kids to The Enchanted Island Amusement Park in Phoenix, Arizona most like
would have sounded like a ridiculous stretch?
Well... Same thing with Disney. The idea of saving up for a trip there for ten years, or the idea that Disney Land is something one has to experience, or is the ultimate vacation target,... is a uniquely US-American thing. Disney parks, to the rest of the world, are just another flavor of amusement park. If you're in the vicinity, sure, why not spend a day. But traveling across the Atlantic for it? No way, not worth it at all, we have amusement parks here.
So "lacking reading comprehension" it is, then.
