Both Altonville & Sleepover have been fantastic. Thoroughly enjoyed both experiences.
Didn't think I'd enjoy Altonville after doing Scare Rooms last year.. and it essentially being the same. Can see that the story works far better being a Scare Room, but it was really good nonetheless.
Hope they continue these things next year. Pricing needs working on, but for £30 for altonville I thought was about right (AP discount there).
