For three days this week, parts of Dublin, Meath, Kildare and Galway were temporarily shut down to accommodate Kate and William on their first trip to the Republic.
This royal visit was a lesson in professional charm. They played hurling; they shopped at Londis; she wore Dubarry.
Much of the softening dates back to Princess Diana, the most famous woman of her generation. At the time of her 1981 wedding, the monarchy was facing yet another crisis (when is it not?) and she emerged as a breath of fresh air and trailblazer.
Angie Grant, managing director of brands at Teneo Ireland, says that memories of Diana are still fresh for many, and her sons represent the next generation of that enduring popularity.
"A lot of people had, and have, deep affection for Princess Diana in Ireland across generations," she told the Irish Independent. "She was the first royal that became a global icon through her charity work and fashion. After her passing, a lot of people were invested in William and Harry, and their futures. They are among the very few celebrities at which you are present for big moments in their life: christenings, first day of school, graduation, their weddings.
"When William married Kate in 2011, it was the start of an amazing partnership and brand. We bought into the fairytale and pageantry of the wedding, and we want them to live happily ever after. They are the most personable brand, both wholesome and relatable."
Paul Costelloe, the legendary Irish designer, responsible for several of Diana's most iconic looks, said the trip was a resounding success.
"I think we've always been interested in the British royal family and it gets more exciting every month.
"Kate and William are the ambassadors for the youth of the royal family.
"I think they were such a great success and she looked great in Dubarry," he said, joking it keeps him "humble" that she chose not to wear the tweed Paul Costelloe jacket hanging in her wardrobe.
On Thursday, hundreds gathered around Galway's Shop Street to catch a glimpse of the couple, who scheduled a walkabout after a trad session in Tig Chóilí.
Michelle Rogers Dunican, a community nurse from Abbeyleix, had lived in London during the 1990s. She followed Diana's engagements and became transfixed by the late princess.
"One day when I was 19 and doing nurse training in London, Diana happened to be visiting the local theatre, so I thought I would go have a look. I waited for three hours in the rain and wind and she came over to meet us, and I was hooked! I used to look up the court circular in 'The Times'. I always had a bouquet of flowers and my camera. I met her 37 times to be precise."
Later in life Michelle launched an independent photo exhibition, showcasing the images she had taken of Diana.
She travelled to Galway on Thursday, ensuring she had a framed copy of one of her favourite Diana pictures to gift to William. It was a picture from June 1997 at the Royal Albert Hall, just weeks before Diana's death.
"I found it interesting that the crowds in Galway were just as interested in William as Catherine," she said.
The age profile of those gathered to catch a glimpse varied from newborns to seniors.
For the less aged, the Troubles are for history books, and the Cambridges represent an appealing, youthful rebrand for the royals - the first couple who seemingly don't have a habit of being in crisis.
