Holiday on the Buses - still

1 - Still from the final moments of the movie showing Stage 06 at MGM Borehamwood being demolished.
As well as location shooting at such exotic UK holiday spots as;
- Dyserth Falls at Prestatyn, Wales
- Gwrych Castle in Abergale, Wales (main part of mystery tour - grounds only shown)
- Rhyl sea front
- Rhuddlan in Wales (bridge where suitcases are lost)
- the holiday camp shown was Pontins at Pretatyn Sands - Pontins at that site is still open (http://www.pontins.com/holiday-parks/prestatyn-sands/), although it's been refurbished a number of times since 1973!.
- The production was based at Elstree Studios, and the final moments of the film show the demolition of a soundstage at the MGM Borehamwood / MGM British Studios. Stage 06, formerly the base for The Prisoner production, is shown being torn down (see below - photo courtesy of Al Samujh)
