His father honeymooned at Broadlands in Hampshire and Balmoral with the late Princess Diana and at Balmoral with Camilla. But where will Prince William choose for his honeymoon with Kate? Possibilities include the following:
KENYA
William has often said his heart is in Africa and Kenya is a likely spot.
The prince first went to the exclusive Lewa Downs nature reserve shortly after his mother's death in 1997 and he spent his gap year there too. Choosing to propose to Kate in Kenya cements his love for the country. Kenya also has poignancy for the Queen. She was holidaying at Treetops, a reserve close to Nairobi, in 1952 when she was told that her father had died and so she had succeeded to the throne.
SEYCHELLES
The couple is rumoured to have made a commitment to marry three years ago, while on a holiday in the Seychelles — and they may make a nostalgic return there.
They had an intimate break on the tiny island of Desroches in the Indian Ocean in August 2007.
After having a "blip" and breaking up with Kate five months earlier, William was apparently keen to show he was prepared to commit. With a population of only 50, a lone hotel, about 20 villas and a single airstrip, Desroches would be an ideal way to ensure privacy.
SCOTLAND
They are likely to spend at least part of the honeymoon in the country where their relationship first blossomed. There have been six royal honeymoons at Birkhall, Prince Charles's residence on the Balmoral estate, including the Queen and Prince Philip's in 1947. Kate's parents were photographed shooting there recently.
Royal author Ingrid Seward said: "It is not only a tradition among the Royal Family but in Kate and William's case Scotland is very much a big part of their love story. They love Balmoral. It is where their relationship grew."
MUSTIQUE
The private Caribbean island is a holiday favourite with Kate's family and she and William have spent several romantic breaks snorkelling, jet-skiing and sunning themselves on its golden sands.
TANZANIA
The couple could choose the Mkomazi game reserve, close to Mount Kilimanjaro in Tanzania.
Even on his honeymoon, William will want to show the seriousness with which he is taking his responsibilities by supporting his charities and promoting tourism in various needy areas.
AUSTRALIA OR NEW ZEALAND
William was mobbed on his tour Down Under earlier this year. Given the growing anti-monarchist movement in Australia — a second referendum on it becoming a republic is expected — it would be a diplomatic move to honeymoon there. New Zealand could be another option.
CRUISE
Charles and Diana spent the second part of their honeymoon — between Hampshire and Balmoral — on the royal yacht Britannia.
Their two-week cruise took in Algeria, Tunisia, Sicily, the Greek islands and Egypt. Britannia has been decommissioned but the Hebridean Princess, which the Queen chartered for the Royal Family's summer holiday this year, could provide a secure location for William and Kate.
Regal coincidence
Although the public knows her as Kate, it is Catherine that she was called when the engagement was announced. Royal aides said pointedly: "Her parents have always called her that. It is what she is called."
When William is crowned and she becomes Queen Catherine, she will be following in a long royal tradition. There have been five Queen Catherines in England's history:
Catherine of Valois
The wife of Henry V, she reigned for only two years before the death of her husband in 1422. Their son Henry VI took the throne when he was nine months old. She died in 1437 and was buried at Westminster Abbey but her coffin was allowed to remain open for all to see between Tudor and Victorian times, before it was finally re-sealed.
Catherine of Aragon
She married Henry VIII in 1509. Their marriage lasted 24 years but was blighted by stillbirths and the premature deaths of male heirs. Henry was so desperate to have the marriage annulled that, when the Pope refused to give his consent, the king spurned Rome and created the Church of England.
Catherine Howard
Henry VIII's fifth wife was beheaded after two years of marriage, in 1542, on the grounds of treason after being accused of adultery.
Catherine Parr
She married Henry in 1543 and reigned as queen until his death in 1547. But she barely saw her husband because he was in battle.
Catherine of Braganza
The Portuguese princess married Charles II in 1662 but was seen as a foreigner and was unpopular with the public.
The couple had no surviving children and she was given the cold shoulder by her husband.
