April 27, 2011— -- Buckingham Palace has been traditionally associated with formal dinners and regal waves by royalty from high balconies. But when the lights go down Friday night after Prince William and Kate Middleton's royal wedding, the queen's primary residence will be party central.

"They've got a hair-letting down. I think we call it in England ... a knees up," Dickie Arbiter, former press secretary to the queen, said on "Good Morning America" today. "That's exactly what it's going to be. It's going to be a sit-down dinner and then a band and disco."

In a royal wedding "first," William and Middleton have elected to have an evening party for an intimate circle of 300 family and friends.

The evening, hosted by Prince Charles, will include drinks, a sit-down dinner, speeches and dancing.

Three rooms on the west side of the palace have reportedly been set aside for the occasion; notably the gilded red and gold throne room, traditionally used for visiting heads of state.

"It's going to be what William called the chill-out room, where the people are fairly tired, they can go in there and relax," Arbiter said.

Couches have reportedly been brought into the throne room for the occasion and drinks will be served.

Royal Wedding After-Party, Disco Balls Included

A larger room, the ball room, will also be used quite possibly as a disco. Measuring 120 by 60 feet, it is the largest room in the palace.

Middleton's sister, Pippa Middleton, is an event planner herself. She has reportedly taken it upon herself to install several actual disco balls in the palace for the party, much to the apparent chagrin of some palace staffers.

"I'm not sure I want to see glitter balls in the palace," ABC News contributor and royals expert Katie Nicholl said. "There's more than enough bling in there."

William's decision to have such a party comes as no surprise to royal insiders. They said it's symptomatic of a new generation of royals poised to inherit the throne in the not-so-distant future.

"That's the sort of character that William is. He's very easy. He's very relaxed," Arbiter said. "He doesn't have to be as formal as his father was."

What a couple usually does after the wedding, Nicholl said, is go straight to their honeymoon. "This is changing the guard a little bit," she said.
