Royal wedding may bring big economic boost for UK

The big day is more than just a happy occasion.

"We are very fond of the royals throughout the Americas," said Gavin Landry, who covers the Americas for the British tourism authority, VisitBritain.

"It's a pop culture phenomenon in some ways," he said.

According to British-based strategic consulting company Brand Finance, the upcoming royal wedding could lead to a £300 million (roughly $405 million) increase in tourism.

The company also estimates that there would be hundreds of millions of pounds accrued through spending in restaurants, in fashion based on the clothes Markle wears to public events both before and after the wedding, as well as merchandise and overall public relations value for the country as a whole.

And for those looking for a keepsake, famed British ceramics manufacturer Emma Bridgewater has a commemorative mug for sale, which extolls the betrothed as “game changers, free spirits, big hearts & well suited.”

VisitBritain reports that tourism accounts for £127 billion annually, or approximately $171.5 billion.

More than 100,000 people are expected to flock to Windsor for the wedding, according to the Thames Valley Police.

Airbnb, the home-share company, said that its hosts will be taking in an estimated 42,000 guests in London between Friday, May 18 and Sunday, May 20.

While the company did not provide the exact number of properties that will be taking in guests, the total host income from that period is expected to be more than $16.9 million.

Americans are the biggest population using the company to find their British digs, followed by visitors from France, Germany and Australia.

"People kind of see themselves in that stage of their lives," he said.

London isn't the only beneficiary of the increased tourist traffic, however. Airbnb reports that the town of Slough, which is just a 10-minute drive from Windsor Castle, is seeing a 1,438 percent spike in guest arrivals over the wedding weekend, as are nearby Maidenhead, with a 362 percent increase, and Windsor itself, with 194 percent increase, as compared to the same time last year.

VisitBritain reports that their overall expectations for the year are up 4 percent as compared to 2017, which was a record-breaking year itself with 38.9 million visitors. The company expects 2018 to hit 41.7 million visitors.

While Harry and Meghan are the big draws this weekend, the monarchy always serves as a draw throughout the year. There were more than 10 million visits to a castle historic house in the U.K. in 2016 and those visits added up to more than roughly $10.8 billion, VisitBritain reports.
