In new details released Wednesday from the prince’s office at the palace, Kate – who turns 29 next Sunday – will wed William, 28, in a service set for 11 a.m. at Westminster Abbey.
The service will be followed by a reception given by the groom’s grandmother, Queen Elizabeth, and the day will conclude with a private dinner and dance at the palace for many of the couple’s family and friends. William’s father, Prince Charles, will serve as host.
The night before the wedding, the bride-to-be will stay overnight in central London at one of the palaces, either Clarence House or a private address, a royal source tells PEOPLE.
According to a news release, MIddleton’s route to the service will take her past some of London’s most famous sites: The Mall (before Buckingham Palace), the Horse Guards Parade, Whitehall and Parliament Square.
The Dean of Westminster, the Very Rev. Dr. John Hall, will conduct the service, and the Archbishop of Canterbury, Dr. Rowan Williams, will marry the couple, the palace confirms. The Bishop of London Dr. Richard Chartres, a friend of Prince Charles and his sons, will give the address.
When they are married, William and Kate will exit to cheering crowds and take what the palace calls “a Processional Route in a carriage procession” to Buckingham Palace.
PEOPLE has learned that the guest list is still being finalized and the invitations have yet to go out.
