While it's where All England Club patronKate Middletonand other members of the royal family are often seen during the tournament, invitations to sit there are extended by the club's chair — not the royals themselves. "British and overseas Royal Families are invited as well as heads of government, people from the world of tennis, commercial partners, British armed forces, prominent media organizations, supporters of British tennis and other walks of life," theWimbledon websitesays about how to score a seat. The courtside Royal Box has served as a VIP area since 1922 and includes access to a private clubhouse for lunch, along with a "smart" dress code. One specific rule stands out: no hats — so as not to block the view of the guest seated behind you!
