Catherine Zeta-Jones' kids keep their feet on the ground with regular holidays to a budget holiday park in the actress' native Wales.
The Oscar-winner and Hollywood superstar husband Michael Douglas have two children, Dylan and Carys, and own homes in New York, Bermuda and Spain.
But despite the family's estimated $177 million fortune, their offspring are kept down-to-earth by their maternal grandparents, who take them to low-cost British holiday chain Butlins and relish the English rainy weather.
The actress tells Stylist magazine, "They love going to Butlins with my parents for long weekends.
"They've been on the beach when it's been horizontal rain in Swansea (Wales), you know? They can't believe it; they're on the beach and it's raining."
Despite their simple tastes, Zeta-Jones admits she's upset the pair don't share her passion for British food.
She adds, "They don't like Branston Pickle, to my horror. They don't like Yorkshire puddings, to my horror. They love a good shepherd's pie because they've been brought up with it, because it's pretty much all I can make fantastically well."
