The holiday season brings with it a variety of rules for members of the Royal Family. From annual celebrations at Sandringham to Christmas Eve gift-giving customs, the Royal Family has little time to stop and think during the holiday season. However, according to a former royal butler, Prince William has allowed himself to have fun at Christmas parties in the past.

Speaking to Slingo via the Express, Grant Harold, a former butler for the royal family, said, “I remember going to one [party] at St. James's Palace and playing with Prince William, Prince Harry, and Camilla I remember that,” he said. According to Harold, the event soon became quite rowdy, and William apparently even got into a “fight” with a staff member.

“I remember there was a water fight going on between another staff member and Prince William. 'It was always very festive and we felt welcome and included in the celebrations.' We were always invited to the family Christmas parties, which was very exciting.”

Harold also noted that when Prince William attended the water fights, “everyone had a blast.”

Meanwhile, Paul Burrell, another former royal butler, opened up about the changes that will take place when Prince William becomes king. I think it is already changing shape,” Burrell told ‘Marie Claire’ on behalf of Spin Ginny. 'The monarchy is changing and the coronation honeymoon seems to be over. [When William becomes king, the Middletons will join him and his wife ....... They will spend Christmas at Sandringham.

Princess Diana's former butler also predicted that William would “clear out the overdressed people, the people who shouldn't be there, and it will be a very family Christmas, not a court Christmas.”
