Look, there's a way that works for both realism and Sci-Fi.
If it's a Vacation Theme Park world - Galaxy's Edge translated into the Sims.
As I understand it Galaxy's Edge is basically a LARPer's dream - or would be if the No Adult Guests in Costume rule didn't apply. It's a fully immersive park, where everyone has characters and there are story lines to follow and the whole shebang. It's Dream Park.
So it feels immersive and like a sci-Fi world, but it's also just a Theme Park, where sims go to get away from reality for a few days.
I mean, I can't speak for everyone, but going to Disney World is about the most iconic "Family Activity" I can think of that doesn't involve dealing with relatives you only tolerate because they're related. Yes, it's just one part of the Disney Complex, but it's still Disney.
