Think about the Wizarding World of Harry Potter in Orlando specifically.
You can buy your school robes and wands, take the train from one area to another, write a letter for the Owl Post, eat in universe foods and "cast spells" in various locations. That's about as immersive as the Starcruiser was, with the main difference being you can't stay overnight.
@lazyboy97o mentioned the time and money commitments. Wizarding World has none beyond general admission. You can do all of the above, or none at all. It's entirely up to the consumer. Even if you want to do everything, if at any point you want a break, you can leave and do something else. It's immersive, but not restrictive.
Epic Universe will have Power Bands for Nintendo and supposedly baby dragons you can adopt in the HttYD area. Each land has some sort of interactive gimmick that comes at a price, but is entirely voluntary. Universal seems to have figured out the balance of interaction and immersion for its parks while Disney struggles with weak imitations. I was honestly expecting Galaxy's Edge to be more like Wizarding World in that sense. Not just mobile games and clothes you can buy, but not wear.
