President Donald Trump's adult children will get two dinners with the British royal family next week when they join the president and first lady Melania Trump on their five-day trip to Britain, France and Ireland.

Ivanka Trump, Jared Kushner, Don Trump Jr., Eric Trump, and Tiffany Trump will all participate in what a source close to the administration is calling the 'family events' during the trip.

That will include a lavish State Banquet at Buckingham Palace hosted by Queen Elizabeth II and a dinner at the U.S. ambassador's home hosted by the president and first lady where Prince Charles and Camilla, Duchess of Cornwall, will represent the queen.

The source described much of the trip as a 'family thing' and said 'the whole [Trump] family is going over.'

The trip will give the opportunity for the younger Trumps to meet some of the younger members of the British royal family.

William and Kate, the Duke and Duchess of Cambridge, are expected to attend Monday night's glamorous white-tie dinner at Buckingham Palace.

Meghan Markle, the Duchess of Sussex, will miss the visit as she is on maternity leave after giving birth to baby Archie about three weeks ago.

Harry, the Duke of Sussex, is expected to attend a luncheon with the first couple and the Queen on Monday.

The young Trumps will be a part of the most elegant events of the visit - particularly the state dinner, which will feature men in white tie, women in ball gowns, the Queen and other royals decked out in tiaras and state jewels.

Buckingham Palace staff will spend three days laying the table for Monday's state banquet - as napkins are folded like dutch bonnets, six glasses are set out per guest and a special cushion is placed on the Prince of Wales' chair.

Their plates will be placed exactly 18 inches apart - precisely measured by staff - and glasses and chairs will all be the same distance away from the table edge.

Each guest will have six glasses - for water, a champagne toast, red and white wines, dessert wine and port.

Overshadowing the glamour will be the thousands of protesters expected to come out in London, including the baby blimp figure of the president, which was present on his working visit to the UK last July.

The owners of the blimp were given permission by the Greater London Authority, headed by Mayor of London Sadiq Khan, to fly the blimp over London during the state visit.

Organizers plan to fly the blimp - which depicts Trump wearing a nappy and clutching a mobile phone - over Parliament Square on Tuesday, the second day of the state visit.

UK officials, meanwhile, have expressed delight the Trump children will be joining the president.

'It's rather a nice thing that he's coming with all of his family and rather flattering they all want to come,' a UK official said.

All the president's children but 13-year-old Barron Trump will in attendance.

The president's children won't participate in any of the government-related events on his itinerary, which will occupy most of the daytime hours, with the exception of Ivanka, who works in the West Wing as an adviser to the president.

The first daughter 'will be participating in official and ceremonial events in London,' a White House official told DailyMail.com.

A UK official said Ivanka Trump could attend a Tuesday morning breakfast with the president; Prime Minister Theresa May; Andrew, the Duke of York; and UK business leaders.

Ivanka Trump could also meet with some UK cabinet officials who work on women's issues - part of her portfolio at the White House.

But both UK and American sources stress the details for the visit are still being finalized and nothing official has been announced.

The source close to the administration said the Trump children will also join the president and first lady Melania in France on the D-Day landing anniversary on June 6.

Some - but not all - of the Trump gaggle are expected to spend time at Trump Doonbeg, the president's golf course in Ireland that Eric Trump oversees.

And Ivanka Trump will peel off on Wednesday to lead the closing session of the Global Entrepreneurship Summit in The Hague, The Netherlands, the State Department announced last week.

Senior administration officials declined to comment on the Trump family schedule when speaking to reporters on Thursday ahead of the visit.

President Trump and Melania Trump arrive in London on Monday, where they will spend three days in Britain before heading to Ireland.

They will also travel to France on Thursday to mark the 75th anniversary of D-Day - the day during World War II on which Allied forces invaded northern France via beach landings in Normandy.

'The dates for D-day are pretty fixed. This is the 75th commemoration, and we felt - all of us - that is extremely important. The President has said this over and over again about the unshakeable bond between the two countries,' a senior administration official said Thursday of the trip.

Kicking off the visit on Monday will the ceremonial welcome being staged in Buckingham Palace's garden. The Prince of Wales and Duchess of Cornwall will join the Queen for the event.

That will replace the usual Horse Guards Parade venue in Whitehall - a decision likely due to security concerns.

There will also be a state banquet for the president that evening - a lavish white-tie dinner staged in Buckingham Palace's ballroom.

The Duke and Duchess of Cambridge will join the Queen and Charles and Camilla for the event, which will feature leading figures from UK national life and prominent Americans in Britain.

Buckingham Palace released the itinerary for the president's three-day visit to the UK earlier this week.

After the official welcome on Monday, the Trumps will have a private lunch with the Queen.

Prince Harry meet the president, but the Duchess of Sussex, American actress Meghan Markle, will avoid a potentially awkward meeting with the leader, who she vocally campaigned against in the 2016 U.S. election.

During President Trump's private lunch with the Queen and Prince Harry, Her Majesty will invite him and the first lady to view a special exhibition in the Picture Gallery, which will showcase items of historical significance to the United States from the Royal Collection.

After this, the first couple, accompanied by Prince Andrew, will visit Westminster Abbey, where the President will lay a wreath at the Grave of the Unknown Warrior.

They will then be taken on a short tour of the Abbey.

The first couple will also have tea with the Prince of Wales and the Duchess of Cornwall at Clarence House.

It will be the first meeting of the president and the prince since Trump entered the White House.

On Tuesday, Trump and out-going Prime Minister Theresa May will co-host a business breakfast meeting, attended by The Duke of York, at St James's Palace, with senior UK and US business leaders.

The visit comes as May announced she is stepping down after three years in power amid the nation's Brexit crisis.

And it comes amid a power shift in the UK. Nigel Farage's new populist Brexit party trounced the Tory and Labour parties in Sunday's election, securing an extraordinary 29 members of parliament.

Farage was them main campaigner for British withdrawal from the European Union.

The Prince of Wales and The Duchess of Cornwall will attend the dinner on behalf of The Queen.

On Wednesday, the final day of the visit, the Queen, accompanied by Prince Charles, will join the Trumps and will attend the National Commemorative Event for the 75th anniversary of the D-Day landings at Southsea Common, Portsmouth, alongside more than 300 D-Day veterans.

Previously, Queen Elizabeth II has also hosted two other U.S. presidents – George W. Bush and first lady Laura Bush in November 2003 and President Barack Obama and first lady Michelle Obama in May 2011.

Additionally Trump will attend a ceremony in Normandy, France, for the 75th anniversary of D-Day.

And the president's scheduled a stop in Ireland to golf at Trump International Golf Links & Hotel Doonbeg Ireland.

While there, Trump will also meet with Irish Prime Minister Leo Varadkar in Shannon, Ireland, which is just a few dozen mile trip by air to his resort on the eastern coast of the European country.
