Kate Middleton ‘couldn’t be more friendly and more open’ during Mustique vacation, traveler says

And these attributions were reiterated by jeweler Martin Katz, who met the Duke and Duchess of Cambridge while vacationing on the island of Mustique with his wife back in 2008.

“I was standing at the [hotel] bar ordering one of the fancy drinks and Kate actually came up to the bar and was quite pleasant and chatty,” Katz told People. “She couldn’t be more friendly and more open.”

The words of praise, of course, didn’t refer only to the Duchess, as the traveler recounted his encounter with her husband, Prince William.

“We started talking about scuba diving. They had gone that day or the day before, and while I was talking, I was holding a glass of fruit punch and it slipped from my hand and crashed to the floor and sprayed all over the prince’s feet. He was in flip-flops,” he said. “I was mortified of course, but all I heard was, ‘That was quite refreshing, thank you.’ His mother would have been quite proud that he handled himself with such dignity.”

Speaking of scuba diving, Duchess Kate recently earned a Professional Association of Diving Instructors (PADI) Advanced Open Water Diver qualification. She can now practice this sport during her next holidays in Mustique with her husband, and she can dive up to a depth of 98ft.

The Island of Mustique is the Royal couple’s favorite holiday destination, after they went there for the first time in 2008.
