Royal wedding: Further details announced
More details of the royal wedding have been released by Clarence House.
Kate Middleton and her immediate family will spend the night before the wedding at the five-star Goring Hotel in Belgravia, central London.
Clarence House also revealed the exact timings of the big day, and the route of the carriage procession.
Meanwhile, Prince Harry has joined Miss Middleton for a wedding rehearsal at Westminster Abbey, where she will marry Prince William on 29 April.
Harry is best man to his brother - who is the second in line to the throne - and plays an important role in the ceremony.
Kate's maid of honour - her sister Pippa Middleton - and her young bridesmaids and pageboys also attended the run-through.
William, an RAF search and rescue helicopter pilot, did not attend as he was on duty.
Earlier, Clarence House said William and Harry would arrive at Westminster Abbey in a state limousine at 1015 BST - leaving almost 40 minutes before the ceremony begins.
It also gave details of the planned flypasts after the wedding.
Three aircraft from the RAF's Battle of Britain Memorial Flight - a Lancaster, a Spitfire and a Hurricane - will be followed by two Typhoons and two Tornado GR4s in box formation.
Clarence House also said the route of the carriage procession would pass along The Mall, Horse Guards Road, Horse Guards Parade, through Horse Guards Arch, Whitehall, along the south side of Parliament Square and into Broad Sanctuary.
The wedding service will be relayed to the gathered crowds by speakers along the procession route, with tens of thousands expected to hear the couple exchange their vows.
There will also be screens at Hyde Park and Trafalgar Square.
A special website has been set up for people wanting to know where to watch the service in central London.
