Considering everyone under the sun in the theme park world is getting in on the LARPing in the park trend, I wouldn't be surprised.
I think it's the only way to make lands like Zelda/Pokemon really feel complete. You should be solving puzzles in a temple in Zelda.
How they can make it work at a scale seen in Disney/Uni parks is what I worry about.
Just brainstorming if they combined immersive theatre into a queue for a ride that can push 2,000 people per hour, essentially by making it and dividing into 10 interactive areas that can hold and entertain 200 people in each section for 6 minutes before moving on, it would be possible. Issue would be space for all the areas to hold all those people which suggests a lot of vertical structures rather than single story facilities.
With that each ride vehicle would have to be able to hold 34 people and be able dispatch every minute or 78 people and dispatch every 2 minutes.
I can see that if they did a pokemon snap/kilmanjaro safari pokemon attraction.
Making and forcing every attraction to now be a minimum hour long interactive experience makes it so its impossible for someone to do all in a park in a day.
Roaming/exploring/bathroom breaks around the park would take an hour of someone's day.
Dining for 2 meals would take two hours.
Time in gift shops ranges depending on person from 30 to ???
If the park is open 12 hours, they would really only hit 9 attractions and if 15 of the rumoured 20 attractions did this and had the capacity of 2,000 people per hour. Meaning it would still take them two days to do everything within the park.
The park minimum capacity would be 30,000 assuming everyone was the queue of the attraction with people entering/exiting within a 10 minute range of each attraction.
However at the same time as long as people are entertained/simulated and not just standing around, guest satisfaction should remain high
