They're one of the world's most famous families with butlers at their beck and call.
But when it comes to keeping her kids entertained during the school holidays, it turns out Duchess Catherine is just like us... with a few minor adjustments!
According to a new report by the Daily Mail's royal correspondent, Rebecca English, Kate recently treated her two oldest children Prince George, five, and Princess Charlotte, three, to a fun day out of swimming in an indoor pool.
The only catch?
The pool in question was at a luxury Norfolk hotel near their country headquarters, Anmer Hall.
The report reveals the Duchess of Cambridge slipped into the five-star hotel on Tuesday, February 19th with George and Charlotte in tow.

The royal trio headed to the pool where Kate opted for a maroon-coloured swimsuit, full make-up and pearl earrings.
Her youngest child Prince Louis, who turns one in April, was most likely back at Anmer Hall with the family's nanny Maria Borrallo.
Onlookers quickly spotted Kate and her kids but the family were left alone as the little ones showed off their diving skills while their proud mum watched on.
"Kate looked stunning. She had full make up one while she was in the pool. And she had drop pearl earrings and her engagement ring. Her hair up in a butterfly type hair clip and looked extremely elegant," a witness told the Daily Mail.
Adding of George and Charlotte's impressive behaviour: "The children were very well behaved and both were practising their diving from the side."
"Kate was organising little races for them and they did it around four or five times. She said 'ready, steady go' and did a downward chopping action in the water to indicate the start of the race."
"He was swimming front like a dog paddle style and jumping in from a squatting position the side."
"Charlotte was doing sitting dives. She was squatting on the side with her arms up in dive position, she kept saying 'Look mummy I'm diving in.'"
"Kate was very encouraging. At one point George went under and Kate had to grab him, he became a bit tearful and clung to her but then he soon went off again."
"Both the children swam unaided and were super confident. They went under the quite forceful jets in the water. Kate politely asked us if it was OK for them to switch it on."
"They were doing little jumps off the side into her arms. Kate did not move from their sides. George did ask to go outside to use the hot tub but she said 'No,'" the insider added.
After swimming in the pool, Kate and the children headed to the steam and sauna room.
It's believed the Cambridge clan have spent the majority of the British school holidays at their Anmer Hall estate in Norfolk before returning to their Kensington Palace home in London this week for the start of the school term.
