Skyline Pavilion

According to Dorice, the Butlin's in Minehead had its own version of the Millennium Dome. (PROSE: Almost Perfect)

Behind the scenes
Although it remains unnamed in Almost Perfect, the structure which Dorice references is known in the real world as the Skyline Pavilion. Beyond Minehead, there are Skyline Pavilions at Butlins resorts in Bognor Regis and Skegness. The actual name of the structure is used here for disambiguation purposes.
