The idea had come to John Nathan-Turner to set the story in Blackpool when Colin Baker opened a ride there called "Space Mountain." The story would also have been set partially there, with the Celestial Toymaker making strange things happen.

Peri would have been attacked by robot miners in a gold mine adventure ride. The Doctor would have been forced to play a video game whose outcome would decide the fate of the planet.

By the end, the Toymaker would be defeated, and the Doctor and Peri would continue their holiday in Blackpool. (DOC: The Lost Season)
