Five of them will be royal, but the other will be showbusiness royalty. She has even bought an apartment for her mother Doria Ragland near Kensington Palace with a discreet entrance to maintain privacy, according to Grazia. The whole town is still excited.
The wedding is being screened in full on ITV from 09:25 BST as part of a three-hour special of the daily magazine show, This Morning.
The ceremony will take place at the castle's 15th Century St George's Chapel with the Dean of Windsor David Conner officiating. Well, he named Meghan as his favorite royal because she's the only one he knows, and was in London - though not at the Royal Wedding - when Meghan and Harry got hitched.
The 1st Battalion Grenadier Guards sent their best wishes to Eugenie and Jack from Iraq.
Princess Charlotte, 3, daughter of Harry's elder brother Prince William and his wife Kate, will also be a bridesmaid while her brother Prince George, 5, will be a page boy. A reported guest revealed that the big day "seemed like a small, casual but intimate affair-a world away from Meghan's huge marriage to Harry in England".
The royal family is paying for the wedding, but the anti-monarchist group Republic is lobbying Parliament to prevent any public money from being spent on security or other wedding-related costs.
Eugenie's sister, Princess Beatrice, is maid of honour.
The queen, who has only just returned from an extended summer holiday in Scotland, plans to host a champagne luncheon for the newlyweds shortly after the ceremony, and a second reception will be held that night.
"We think we've been blessed this year with two royal weddings", said Phillip Bicknell, the local council deputy leader. We bet there will be a lot of black.
