Ally, I wondered because we always had our Summer holiday in the 70s and early 80s at Butlins, either Minehead or Pwllheli though. It was brilliant! Loads of us would go - my parents, my Nan, aunties and uncles and cousins - and we'd be in adjoining chalets.
Only have to hear Roxy Music's Dance Away and I'm back in Minehead in 79 at the disco (think it was the Beachcomber)
