Who are invited and who are not?
They will form a guard of honour for the royal couple with a half company of 25 personnel from RAF Honington in Suffolk, where the prince is Honorary Air Commandant.
Famed for their plumed helmets and shining breastplates, 24 dismounted soldiers and two officers will line the staircase into St George's Chapel at the castle ahead of the ceremony.
Interestingly, the couple has requested that the crowd chosen include young people from all across UK.
The royal family will meet their future in-laws next week. "She's like this ice queen". However, there is a chance that her husband, Prince Philip, won't make the it. Naturally they have a four-hour feed starting at 5 a.m. EST of the actual ceremony, but that's followed by a special for sartorialists out there: TLC's Royal Wedding Revealed, which will air at 10 p.m. EST.
Is Meghan Markle playing a role?
Like Markle, Ragland will need to learn to curtsy and master the royal traditions of everything from taking tea to table manners and etiquette, as her daughter becomes British royalty. Harry's brother Prince William and his wife Kate Middleton welcomed their third child last month. However, the newest member of the royal family, Prince Louis, will miss the wedding.
Emily Andrews, The Sun's royal correspondent, also confirmed the news on Wednesday's Lorraine.
Perhaps because it's against protocol for royal women to take off their coats in public, Markle's dress was only fully revealed when she and her beau sat for their engagement interview.
In the opinion of her ex-classmates in the acting school in Los Angeles, Meghan Markle was close to her parents. One wrote, "Wow I thought this was a real picture", while another added, "They got her So right!" Most princesses like frogs I heard.
