*blows cobwebs off*
I don't know if it's been explicitly discussed on the forums, but Towers' Entertainment function is now in the hands of an external team, outsourced in a similar way to how food is now outsourced to Aramark. The team responsible for that is RWS: https://www.rwsglobal.com/
I don't know exactly how it now works, and how responsible RWS are for the design of new attractions. However, the 2 new scare attractions for this year are a scare zone and scare maze, both themed and located in the Dark Forest:

It's worth noting that Thorpe's Entertainment function is going to be in the hands of RWS from 2026. So how Scarefest goes down this year might give an indication to how Fright Nights will go next year (which will be marketed heavily due to it being the 25th year)
