I think it could be a Northern thing. Really, pre phones and before most had cars, just a way of visiting relatives? My DF worked on Saturdays, so once a fortnight Mum and I would get the bus to visit her Aunts and cousins a few miles away - this would be the late ‘50s. Tea would be provided with ham sandwiches and cake, etc, and this visit would be reciprocated a fortnight later. Then most Sundays, my Dad’s aunt and uncle, who had a car, would call for morning coffee, then after lunch, Dad and I would get 2 buses to visit his parents about 10 miles away. It was a nightmare in winter, with the return buses often cancelled - we’d stand for hours at freezing bus stops. Then, after I passed the 11+ Mum said I shouldn’t be going, as I had homework - but then I had to accompany DGM to Evensong on Sunday evenings! Out of the frying pan?
My Mum’s mother and her favourite Aunt lived in the same street, so no need for the more ‘formal’ visits there.
