But one five-year-old boy, Max, caught the couple's attention during a walkabout of the Emirates Team New Zealand base.
HELLO! Online spoke to Max's mother Vicci, who talked us through meeting the Duke and Duchess of Cambridge.
"After waiting for four hours, we finally got to meet William and Catherine," she said. "They walked around and shook every single child's hand possible, making time for everybody.
"Prince William came up and shook my hand first. He then looked down at Max – who was wearing a Bournemouth Royal Cadet polo shirt – and said 'Now that's a pretty cool top you're wearing!'
"He also asked us how long we'd been waiting there for. He seemed very considerate."
Kate was behind William in the walkabout, having received lots of flowers and presents from waiting children.
"Kate came along next. After greeting me, she looked down to Max and said, 'Aren't you a little cutie?'"
Vicci was full of praise for the kind couple, who she described as "down to earth. Just like one of us."
She also said that Kate is stunning in the flesh. "She's absolutely beautiful. If someone said one word to describe her, it would be beautiful."
