A bride-to-be who will treading in the footsteps of Camilla Parker Bowles in Windsor on Saturday says it will make her day even more special.
The couple are marrying just an hour and a half after Charles
Grace Beesley, 33, from Essex, and Fraser Moores, 34, will be the first couple to marry in the Guildhall after Prince Charles and his bride.
"It will be just another dimension to the day and a bit more exciting," said Miss Beesley, of Corringham.
The couple will marry an hour and a half after the Royal bride and groom.
"We won't have to make any changes to our wedding - the registrar rang us and told us that," she added.
The prince's communications secretary Paddy Harverson insisted the switch of the Royal wedding from Friday to Saturday would not disrupt Miss Beesley and Mr Moores' day.
"Their guests will be able to get in and out quite happily," he said.
Because roads around Windsor will be closed from 0730 BST and Clarence House is expecting scores of media to descend on the town, Thames Valley Police is holding meetings to establish how to handle other weddings on the day.
Mr Moores said he expected Windsor to be busier as a result of the postponement, but added: "I don't care - bombs could fall from the sky and I'm looking forward to still getting married."
The Prince of Wales and Camilla Parker Bowles will marry at 1230 BST on Saturday, Miss Beesley at 1400 BST.
