It's hard to scale location-based entertainment. Disney tried the Galactic Starcruiser themed hotel, but it was a dud. Too expensive - $5000 or so for 2.5 days. It was a LARP dumbed down to Disney park customer level. Lots of mini-games, not much coordinated activity.
That's about how this sort of thing usually goes. Keeping everybody on script in coordinated activity is tough. I was involved with steampunk conventions, pre-COVID. Those took elaborate prep, but there was no all-player coordinated event.
The US has some events like this. Wasteland Weekend. The Society for Creative Anachronism. Military reenactment groups.
