Instead, hundreds of American anglophiles - armed with colorful hats, Union Jacks on sticks, and boundless enthusiasm - have flown to London to be in the thick of it, even if the throngs may make it hard to actually see the royal couple.
"Who knows when the next wedding of a future monarch will take place?" said Catie Anchin, a 29-year-old fan who arrived with her husband from Washington DC this week.
"This is my chance to see history happen in the flesh."
What is the draw for people without prized invitations to Westminster Abbey?
They say they want to soak up the atmosphere, hoard souvenirs, and, most important, catch a glimpse of the couple's public smooch on the balcony of Buckingham Palace.
That last mission won't be an easy one.
As the tourists scoped out the best spot to stand, they worriedly asked how exactly they could beat the throngs of well-wishers expected to line The Mall on the day of the wedding.
"Holy Toledo, what am I going to do on the day?" said Debbie Achs, a property manager from Mesa, Arizona, as she took in the barricades and the scale of the press stands being set up around the palace and along the wedding procession route.
"If I see the balcony kiss that will be the icing on the cake. I don't think I'll be camping out at 5am, so I'll have to get creative in other ways."
Achs, 54, rushed to book her flight days after William and Middleton announced their wedding date in late November. The wedding provideds the perfect excuse to visit Britain, her spiritual home.
She she has returned every year since 2001 to indulge her appetite for castles and royal history.
Other American tourists have similar stories about their love affair with the royals: Hailing from such a young nation, they're fascinated by the centuries-old protocol, the pomp, and the fairytale stories of princes and princesses.
Some of the women also confess they have a soft spot for William because they watched him grow up on television.
Some cite additional personal connections: Achs, for example, feels an affinity with the late Princess Diana because they were born in the same year and both gave birth to two sons.
Anchin ascribes her lifelong obsession to her birthday, which falls on the same day as that of the late Queen Mother Elizabeth.
Janice Ashby, who arrived Wednesday with a girl friend, has a strategy of sorts to beat the crowds.
"I'm 5 feet 10 inches tall and I'm going to wear stilettos, so hopefully I will tower over all the short spectators and get a glimpse of the royal bride," said Ashby, 54, from Geneva, Nebraska.
She's made her own fascinator - a small feathered or jeweled hairpiece attached to a clip or a comb - for the occasion. Hers is pink and black complete with a big butterfly.
"We never get the opportunity to wear such fun and frivolity," she said. "I will wear my fascinator with pride, and cheer and yell for the royal couple as loudly as if I were at a football match."
Others say they would be content bringing home memories of the day.
"Even if we can't actually see them, we'll hear the horses' hooves on the ground and the creak of the carriages," said Sheree Troy, a 54-year-old collector of royal memorabilia from Lincolnton, North Carolina.
To make the most of her trip, Anchin is also planning to celebrate the night before at Mahiki, the posh nightclub where William and Middleton have been known to party.
Her husband didn't mind.
"Who needs sleep on the royal wedding week?" he said. "I'm ready for it."
