EVENING PARTY

One of the biggest expenses will be the evening party. “The dinner-and-dancing part will be the real celebration,” says Niemierko. “The Queen will most likely not be present, so everyone can let their hair down and have some fun.” The costs of nighttime festivities can easily rack up, he explains. Lighting, sound and bespoke bar designs are pricey, while small touches, such as mirrorballs, have been known to cost $19,000 alone. The other question is whether a famous musical act is to perform. Kate and William held their evening party in the throne room at Buckingham Palace, which was converted into a nightclub for the occasion. This would have cost around $87,000, says Niemierko, while some mid-level acts can command around $174,000 for a one-off performance. But, Niemierko anticipates, “they’re not going to go mad.” “There was a rumour that the Spice Girls might play, but that would cost an average Joe a fortune — about $1.7 million for each band member.”
