Windsor is expected to see a surge in tourists as a result of the Royal Wedding, with the beautiful surroundings capturing imaginations across the world.Tourism experts said the global spotlight thrown on the town – and a television audience of around 2 billion – is likely to mean a boost in the numbers coming to see its historic sights in coming months. Patricia Yates, from VisitBritain, said the images of a fairytale romance in glorious surroundings would prove an irresistable “showcase”.“It’s the fairy story of an American girl marrying a British prince,” she said. “We expect it to lead to a boost in tourists coming over in the weeks and months ahead, who will then travel to our heritage sites across Britain.”The industry anticipates an increase in the number of tourists after idyllic scenes of Windsor Castle, The Long Walk and the bustling town streets were beamed across the globe. Ms Yates said the popularity of the Duchess of Sussex in her home country could only add to the appeal for US tourists.The tourist board expects a 15 per cent rise in visitors from the US, year on year, bringing more than £3.4bn to the British economy. Even before the wedding, tourist numbers rose significantly, with an extra 50,000 visitors arriving in the week of the first May bank holiday, records show.Figures released by the Royal Borough revealed that 201,826 passed through the town in the week beginning Monday, May 7 – a 37 per cent rise on the same week last year, when 147,433 people visited.And Airbnb anticipated a 192 per cent increase in bookings in Windsor over the weekend of the wedding.
