Large lights, screens and lorries parked half way up the hill all today, and a catering van & toilets parked in the car park next to the station with waiting taxis and a security guard.

Any one know what's being filmed?

Yes it was apparently a short advert for a chocolate brand. I know this because one of the producers booked my spare room through airbnb for the night before.

Did they pay you in chocolate?

In a roundabout way yes as I used around 2% of the proceeds to buy a Crunchie.

They could have given away free samples and attracted a huge crowd!

Sounds like they only paid about £30 for a bed at Simonk's, so clearly not that generous!
