LONDON -- Meghan Markle's divorced parents will meet with Queen Elizabeth II and other royals before her May 19 wedding to Prince Harry and will have special roles in their daughter's wedding, a palace spokesman said Friday. At the wedding, the royal couple also plan to honor the memory of the late Princess Diana, Harry's mother, who died in a Paris car crash in 1997. 
 
 Officials didn't predict the weather - springtime in England can be glorious or horrid, sometimes on the same day - but they outlined plans for a celebration designed to spread from the privileged environs of Windsor Castle throughout Britain and the world, via television and the internet. 
 
 Here are some of the plans disclosed by Harry's press secretary, Jason Knauf, during a briefing at Buckingham Palace: 
 
 Meghan's Parents To Take Part In Wedding 
 
 Markle's parents, Thomas Markle and Doria Ragland, will arrive during the week before the May 19 wedding so they have time to meet Harry's family. 
 
 Knauf says they will visit with the queen, her husband Prince Philip, Harry's father Prince Charles and his wife Camilla, and with Harry's brother Prince William and his sister-in-law Kate. 
 
 Ragland will travel with her daughter by car to Windsor Castle on May 19 and Thomas Markle will walk his daughter down the aisle of St. George's Chapel for the ceremony. 
 
 Knauf says Markle is "delighted" that her parents will be by her side. He did not say whether Markle's half brother and half sister will attend the wedding. 
 
 ___ 
 
 Princess Diana's Family Will Have A Role 
 
 The press secretary says Harry is "keen to involve his mother's family in the wedding" and that all three of Diana's siblings will be present. One of Diana's two older sisters, Jane Fellowes, will give a reading during the ceremony to represent Diana's family. 
 
 ___ 
 
 No Maid Of Honor 
 
 Markle, an American actress who came to prominence in the TV series "Suits," will not have a maid of honor during the ceremony. 
 
 Harry has chosen William as his best man. 
 
 ___ 
 
 Young Bidesmaids And Page Boys 
 
 Knauf says all the bridesmaids and page boys will be children. That may mean a role for Prince George, 4, and Princess Charlotte, 3, the children of Prince William and the Duchess of Cambridge. But don't bother looking for Prince Louis - born in late April - as the youngest prince will not attend the wedding. 
 
 ___ 
 
 Don't Ask About The Dress 
 
 Palace officials are determined that the style and designer of Markle's wedding gown will be kept secret until the moment she gets out of the car to walk into the chapel. They say this tradition is very important - but that won't keep speculators from trying to guess who has received the most important dressmaking assignment of the year. 
 
 ___ 
 
 Separated The Night Before 
 
 The press secretary says Harry and Markle will spend the night before the wedding apart. They have been living together in recent months since announcing their engagement. They will spend their first night as a married couple in Windsor Castle. 
 
 ___ 
 
 Good Wishes For Prince Philip's Health 
 
 Palace officials say they're hopeful that 96-year-old Prince Philip, Harry's grandfather, will be well enough to attend the wedding festivities . The queen's husband has been recovering from hip replacement surgery and has not participated in any public events since being discharged from the hospital in mid-April. 
 
 ___ 
 
 Follow The Wedding At Home 
 
 The palace plans to publish the Order of Service on its website the morning of the wedding so people watching it on television will be better able to follow what's taking place inside the church. 
 
 ___ 
 
 Delayed Honeymoon 
 
 Knauf would not reveal where the newest royal couple will spend their honeymoon, but he said they won't be leaving right after the wedding. Instead they plan to make their first public appearance as a married couple during the week following the ceremony. In the past, they have traveled in Africa together.

 Prince Harry was greeted with shouts of "good luck!" from well-wishers as he carried out a surprise walkabout in Windsor on the eve of his wedding. 
 
 With his brother and best man Prince William, he spent nearly 10 minutes chatting to the crowds. 
 
 Just before he went back into Windsor Castle, he was asked how he was feeling and said: "Relaxed, of course." 
 
 Meanwhile, Meghan Markle and her mother, Doria Ragland, arrived at nearby Cliveden House Hotel. 
 
 As she arrived at the hotel following tea with the Queen, Ms Markle said she was feeling "wonderful" on the eve of her wedding. 
 
 During his walkabout, Prince Harry asked people where they were from, and whether they had been waiting long. He was also given a small teddy bear as a gift. 
 
 As he returned to Windsor Castle, the prince spotted his friend, Dean Stott - a former special forces soldier who trained with him for six weeks in 2007 - in the crowd. 
 
 The 41-year-old, who had just returned from a 14,000-mile Pan American Highway cycling trip to attend the wedding, said the prince told him he was "looking skinny" as he had lost weight. 
 
 "If he (Prince Harry) is nervous, he's hiding it very well," Mr Stott said. 
 
 Earlier, Kensington Palace said Prince Charles will walk Ms Markle down the aisle on Saturday. 
 
 Ms Markle's father, Thomas, is unable to attend the wedding, after undergoing heart surgery. 
 
 The Prince of Wales was "pleased to be able to welcome Ms Markle to the Royal Family in this way", the palace added. 
 
 Prince Harry's grandfather, the Duke of Edinburgh, will also attend the wedding, Buckingham Palace confirmed. 
 
 Prince Philip, 96, has been recovering from a hip operation.

 Ms Markle's mother, Doria Ragland, will take her daughter to the wedding at St George's Chapel in Windsor. 
 
 Ms Ragland met the Queen for the first time at Windsor Castle, accompanied by Ms Markle, 36, and Prince Harry, 33. 
 
 She has already been introduced to Prince Charles and the Duke and Duchess of Cambridge. 
 
 The ceremony begins at 12:00 BST and will be broadcast to the world. 
 
 The Archbishop of Canterbury, Justin Welby, who will marry the prince and Ms Markle, said he thought it was "wonderful" Prince Charles will walk Ms Markle down the aisle. 
 
 "He's a very warm person and that he's doing this is a sign of his love and concern and support," he said.

 Mr Markle had been due to arrive in the UK earlier this week, but became caught up in controversy over the apparent staging of photographs with the paparazzi. 
 
 Speaking to the BBC from Windsor, American celebrity news site TMZ's Sean Mandell said he had spoken to Mr Markle on Wednesday and that he was "doing well" and "recovering from surgery". 
 
 Mr Mandell - who broke the story - said Mr Markle realised on Tuesday that he would not be travelling to Windsor. 
 
 "Chest pains were really being exacerbated by the emotional strain he was under," he said. 
 
 "When doctors told him he needed to have surgery, he decided he needed to heed that advice, despite the fact he wanted to be here in Windsor for Meghan." 
 
 Ms Markle released a statement on Thursday saying she hoped her father could be given space to focus on his health.

 During the walkabout, lucky royal fan Jane Toffolo not only spoke to Prince William - but found herself a new job. 
 
 As Prince Harry shook as many hands as he could, greeting well-wishers who had camped out since Tuesday, his elder brother had a cheeky request for Jane. 
 
 "He said he was after a new babysitter and asked if we could do it - he said it to all of us," Jane recounted afterwards. 
 
 And what did she reply? "Of course!" 
 
 Rick Dormer and Nicola Dormer from Salisbury stood next to a young royal fan, also called William, who spoke at length to Prince William - and got a royal high five. 
 
 "When Prince William found out the young boy's name was also William, he said 'well you're the most important person here!'" said Mrs Dormer. 
 
 Ms Markle will spend her last night before the wedding with her mother at Cliveden House Hotel, which is in Buckinghamshire, about nine miles north of Windsor Castle. 
 
 Prince Harry will be staying 15 miles away at the Dorchester Collection's Coworth Park in Ascot, with his brother.

 Ask me hide
– Prince Harry will be missing his mother on his wedding day, just two weeks away, but his aunt will be standing in. Lady Jane Fellowes will represent her sister, the late Princess Diana, at the May 19 ceremony at Windsor's St. George's Chapel, where she'll also do a reading, reports CBS News. Diana's two other siblings also will attend, as will bride Meghan Markle's mother and father, who are divorced. They're to meet the queen, Prince Philip, and the other British royals a week ahead of the wedding, which will see Thomas Markle walk his daughter down the aisle. CNN reports Markle won't have a maid of honor. "She has a very close knit group of friends and did not want to choose one over the other," a rep for Harry says. (Harry's pick for best man is no surprise.)
