In your opening post, you cancelled out Australia, but, the closest park from Sydney, Australia would be Hong Kong Disneyland at 4,587 miles away.
Well, the problem with Australia is that, like all of the Asian parks, this one is located at or near the Pacific.
Australia is its own continent so that may be something to consider - it checks off all your criteria.
And so is South America. Brazil seems like a relatively safe bet (the safest, anyway) in this regard. Probably around Rio, which, as I said, has a partying reputation (when the situation is right). And it just hosted the Olympics, so there's that.
Another thing was, for some reason (I don't really know why), I was thinking of doing a park where German is the main language (I was thinking of doing a replica of the Seven Dwarfs Mine Train with this language for example). And it's not the case in either Australia (English) or Brazil (Portuguese). But I guess those are the two safest bets right now.
