Your South Wales theory could be spot on - have a look at these pictures of Barry Island (I was concentrating on the large building):

Arthur, you are an absolute star!  Not only have you found the location of the beach, it is in South Wales too - exactly where I hoped it would be!

I will now concentrate on the branch of the Dodson family who lived in Cardiff and Llanelli.  There is a girl in that branch born in 1945 which could fit with the girl in the photos.  She is Fred's great niece and Ethel's niece.

Thanks again Arthur for your help
