Aimee Dunne, a London-based wedding planner who specializes in luxury weddings, said that even conservative estimates for a modern royal wedding would start well into six figures. "Traditionally the cost of the wedding falls on the wife's family, but surely this won't be the case here," said Kate Williams, a historian and royal expert. "Of course the situation has changed since the previous royal wedding, so the security requirements will be much stricter," Williams said, referencing a series of recent terror attacks in the city. Charles' wedding to Diana was also declared a special holiday, as was the wedding of his younger sister Princess Anne. Some argue that increased tourism from abroad would help offset the cost of a royal wedding, but the Office for National Statistic found a little evidence of the phenomenon in 2011.
