King Charles has reportedly set himself a strict 6pm bedtime curfew the night before his Coronation to ensure he isn't too tired for the ceremony.
The 74-year-old monarch is a renowned workaholic but is understood to have told aides he won't be doing any royal duties beyond his self-imposed cut off so he's fresh for May 6.
The evening before his big day he is due to host a reception for Commonwealth leaders and there is also due to be a dinner at Buckingham Palace.
However it's believed Charles will slink off early and head to bed.
In contrast, his late mum Queen Elizabeth attended a banquet the night before she was formally crowned in 1953.
At 26, she was far younger than her oldest son.
The Commonwealth Parliamentary Association said "what was appropriate then will not necessarily be appropriate now”.
Charles' Coronation will be stripped back compared to what's gone before in an effort to reflect the financial difficulties many in the country are suffering thanks to Covid and the cost of living crisis.
A source told the Daily Telegraph: “There have been some logistical challenges caused by the King.
“He doesn’t want to do anything in the evening in case it tires him out. There will be no partying.”
Foreign dignitaries and other VIPs will enjoy receptions and other bashes throughout the special bank holiday weekend.
The ceremony itself is expected to see around 2,000 people cram into Westminster Abbey.
A limited number of tickets will be made available to British politicians.
Official invitations are yet to be sent out, though 'save the date' notifications have been posted.
There will be a procession back to Buckingham Palace with the King and other royals to appear on the balcony.
The next day, a concert will be broadcast live from Windsor Castle.
It comes after leaked plans suggest all three of Prince and Kate's children will attend the coronation.
Prince George, Princess Charlotte and Prince Louis will join their grandfather and the Queen Consort Camilla as they leave the Abbey.
Second-in-line to the throne, George, nine, has long been expected to attend the coronation, though it is not known whether he will have a role to play.
However, it has not been known until now whether Charlotte, seven, would be there, nor Louis, who turns five next month.
Prince Harry and Meghan are understood to be on the guest list but it is not confirmed if they will accept any invite.
Reports yesterday suggested they want to be part of the "special family moment" when royals gather on the Palace balcony.
