Yes, the switch from Hardly-Able-son can only be for the better! If I won the lottery I would be very tempted! Interesting to hear about the Shadows' close call with that film, mind you I do like the cheesy music in it, and especially the gorgeous rowdy hot Dixieland Mr. Hulot listens to on the radio (or Gramophone?) while every one else in the hotel is virtually silent and bored stiff, I think it is Nat Gonella and His Georgians.
An Aunt and Uncle of mine Honeymooned in the Hotel de la Plage about 2 or 3 years after it was used in the film, the dining room door creaked just as it does in the film, and almost nothing about the hotel or its contents was different!
