Scotch Corner Hotel
Scotch Corner Hotel was a hotel located south of Darlington. It existed in the full seven dimensions and provided a gateway to the entire multiverse. (PROSE: Enter Wildthyme)
Behind the scenes
Whereas some of the locations set in Darlington from Enter Wildthyme are fictitious (partially due to Enter Wildthyme introducing locations from Exchange which do not exist in reality), the Scotch Corner hotel is a real hotel in Darlington, owned by the hotel chain Holiday Inn.
Location information
Though it's possible that a real world location doesn't exist in the same geographic space in the Doctor Who universe, such cases are few and far between. Thus, the map to the right is probably a good indicator of the DWU location of Scotch Corner Hotel.
