The Terminal sounds like an interesting experience and idea.
The park are working with Darkfield for the experience, who have lots of experience with audio attractions (they very much became the rage during the Covid lockdowns). I believe that usually you do these experiences blindfolded, and it relies on your imagination somewhat. Couple that in with special effects (movements, mist sprays, etc), and it has potential to be a really cool experience.
But. I think this experience suffers from being quite niche in market. I reckon it involves a certain level of buy in from the guest for it to truly work. How many people, at Fright Nights, want to go into a experience and actively participate in making the most of an attraction for themselves, whilst also - somewhat paradoxically - sitting in an enclosed space alone? I don't know, but I reckon it's a smaller proportion of the audience than those who are interested in going into a scare maze.
In turn, it runs the risk of disappointing a lot of people because it may just end up feeling like "sitting in the dark with some headphones on".
I'm not saying that's what will happen. But there's certainly a risk there. Could be a risk that pays off majorly though.
Fair play to Thorpe for doing something which is truly different and not really seen before in a wider market. I really hope it works out well.
