Two small boys playing with a rubber dingy

A picture of two small boys playing with a rubber dingy in what looks like a holiday park. Behind the boys is a narrow gauge railway, and what appears to be a small child abandoned in their push chair!

I’ve dated this picture between 1960 and 1969 based mainly on the short trousers the boys are wearing. To my mind, short trousers went out of fashion in the 1970s, so I think this is before that.
