As a child, my mother spent many of her holidays at Folkestone,Kent, England. It was,at least in part, because her paternal grandparents lived there, so they had a place to stay.
As an adult, her sister spent many holidays at that most English of seasides, Blackpool, England.
My father's maternal grandparents, who were both avid amateur painters (I have some of their paintings) spent many painting holidays in Fiesole, just outside Florence, Italy.
