Disney has problems with that. Their Galactic Starcruiser themed hotel experience cost more to the customer than a cruise on a real cruise ship, and Disney was still losing money on it. The cost merely to visit their parks is now too high for most Americans.
It's really hard to make money in mass market location-based entertainment. There have been many attempts, from flight simulators to escape rooms. Throughput is just too low, so cost per customer is too high.
A little mobile robot connected to an LLM chatbot, though - that's not too hard today. Probably coming to a mall near you soon. Many stores already have inventory bots cruising around. They're mobile bases with a tall column of cameras which scan the shelves.[2] There's no reason they can't also answer questions about what's where in the store. They do know the inventory.
