Later that afternoon, Kate headed to her family’s Bucklebury, Berkshire home to start making wedding decisions.

England’s Prime Minister David Cameron has commented that the wedding should be “a day of national celebration.”

In England, public holidays are referred to as bank holidays. “If it's in the week it would be a very good idea to have a bank holiday,” Cameron said.

“And even if it's at the weekend there would be a great temptation to have a bank holiday.”

A spokesman for St. James Palace says William and Kate are in full support of the idea. "Prince William and Catherine Middleton are grateful for the Prime Minister's comments, they also support the idea of a Bank Holiday but recognize this is very much a matter for the Government."

When it comes to a royal wedding, there is a lot more that goes into planning besides flower arrangements and whether to have an open bar. 

RadarOnline.com gives a rundown on who will really plan this century’s most talked-about nuptials between Kate Middleton and Prince William.

One thing that has marked William and Kate is their modern approach to things and the palace’s allowance of their freedom to tailor their experiences to fit their needs. While security and protocol will be paramount, releases from the palace make it clear that the wedding will largely be based on the desires of Kate and William as much as those of the royal family and the public.

Though Kate was accompanied by senior aides on her recent trip to Westminster, a spokeswoman at the prince’s office made it clear that the couple would consult with their families on the final decision regarding the wedding’s location.

The week of the engagement announcement, Kate headed to her parents’ home in Berkshire to discuss the wedding with her mom Carole and her dad Michael. During the visit, a van from Ambassador Catering (a company specializing in big occasions) was seen on the property.

Despite the couple’s looser-than-usual leash, the palace will continue to lend a steady hand of guidance. A spokesman for St James's Palace said William and Kate had given "clear direction” for dates and venues. "Our job is to consult with the relevant parties - the Queen, Duke of Edinburgh and the Middletons - and report back," he said.

Over the years, Middleton has favored the label Issa from the Brazilian-born designer Daniella Issa. For the couple's formal announcement of their engagement, Kate wore a deep blue dress for the brand, which quickly sold out after her appearance.

She's set to take on the role as the future Queen of England but before she even met her Prince, Kate Middleton was just another schoolgirl with fairytale dreams. RadarOnline.com has photos from her girl next door childhood.

Although Prince William has said fiance Kate Middleton, or anyone else for that matter, is not trying to fill his mother Princess Diana's shoes, royal experts are drawing even more distinctions between the two most important women in the young royal's life.

"Kate and Diana are very different. They come from totally different backgrounds," Claudia Joseph, author of Kate: Kate Middleton: Princess in Waiting, told RadarOnline.com. "Diana hailed from an enormously privileged, aristocratic, old English family. Kate comes from a family that - as you can see from my book - descends from working class mining stock. In many ways, she had a much more modern upbringing."

She's been called "Waity Katie" and with good reason.
