Elsewhere, Kate and her brother Will are making it a family affair with dad John.
“Getting to go to Wembley and see us play in a semi-final is just crazy,” says Will, from Huddersfield.
“It’s our first time going as a full family,” adds Kate. “Unlike my dad, it’s the first time my generation has had a chance to do it. It’s really exciting. There’s a real buzz about the club. I feel there’s definitely an opportunity for us there.”
John agrees Leeds have a “really good chance”, but memories cast a long shadow he hopes this trip can banish.
“I can remember the debacle of the 1970 FA Cup final, when Chelsea took us to a replay and we had all that scrapping on the field, so to get one back on them would just be fantastic.
“It marks the return of the club to our former glory. It’s brilliant for me as an old fella to see us back up challenging for silverware again.”
Some fans will be heading to London to both create and watch sporting memories.
Adam, from Leeds, will see his son Josh run the London Marathon before heading to Wembley.
“I want to win it now, for sure,” he says. “We’re probably safe in the league so it would be mad not to.”
Jack, from Rastrick, has flown in from the Middle East, where he is a member of the Dubai Whites. He is doing the London Marathon and Wembley double and will meet up with his dad Paul, who inspired him to pound the streets to raise money for the British Heart Foundation.
“I was praying [the cup semi-final] was going to be on the Saturday so I didn’t have to crawl there,” he says. “But how often do you get the chance to do two things like this? I just had to do it.”
Then there is Molly, who follows the Whites home and away with her dad.
“Hopefully this is just a rehearsal before the final,” she says. “From Yeovil to cup semi-finals, that’s why you do it.”
And what does it mean to be there with her dad?
“So much,” she says. “I could cry. I’m sure I will be… walking down Wembley Way with him.”
