Erin McGregor tied the knot with Irish singer-songwriter Terry Kavanagh on Saturday, Aug. 17, at the luxury Cashel Palace Hotel in Tipperary, Ireland, surrounded by 135 guests.

Erin, 43, tells PEOPLE she and Terry, 47, chose to host their wedding in Ireland because "home is where the heart is," adding, "Everyone asks why we didn’t get married abroad, and the truth is wanting our son Harry to be a part of our day was more important."

Harry, 8, has autism, so Erin says the wedding was carefully planned around his needs and well-being, with help from event planner Andrea Winckworth of Andrea Winckworth Events.

"Our absolute must-have for the wedding was ensuring that Harry was as comfortable as possible and able to enjoy the wedding festivities. To achieve this, we put several thoughtful measures in place to maximize his comfort and joy," Erin explains.

Those measures included holding the ceremony outdoors "to give Harry the freedom to roam as he pleased without feeling confined to an indoor space," having several therapy animals on hand including two ponies and Harry's own support dog, and setting up a sensory-friendly retreat for Harry at the venue.

For the couple, their wedding was also a special opportunity to bring together all of their family and friends — "the people who have seen us at our best and worst moments" — to "celebrate our happily ever after," Erin says.

On the morning of the wedding, in a special gesture, Erin gifted her bridesmaids — who included her 24-year-old daughter, Taylor, and Conor's fiancée, Dee Devlin — customized blue pajamas (in a nod to her "something blue") and dressing gowns from her own brand, Imperfection by Erin.

The bride and groom opted for an "unplugged" wedding ceremony, asking their guests "to be fully present in the moment without distractions," Erin explains. They performed traditional vows and enjoyed live music by singer Rebecca Creighton and accompanist Ewan Ferguson on a white baby grand piano. Several family members gave heartfelt readings, and Erin and Terry exchanged rings from The Cut Price Jewellers.

Accompanied by her father, Tony McGregor, Erin walked down the aisle to a mash-up of two songs with special meaning to her and Terry: "Simply the Best" by Tina Turner and "This" by Megan McKenna. She wore a white Zuhair Murad gown, purchased from The Wedding Club in London, and Jimmy Choo shoes.

Erin says she was immediately drawn to the dress' "intricate lace detailing and luxurious fabric," noting: "The gown perfectly complemented the regal and glamorous theme of the wedding, making me feel both sophisticated and radiant."

Understanding that Harry might not feel comfortable joining the other page boys and flower girls as they processed down the aisle, Terry and Erin found a unique way to include their son in the experience.

"To still capture this special moment, we recorded a video during the rehearsal of Harry walking up the aisle with us, which we played on two TV screens during the ceremony," Erin tells PEOPLE. "This allowed us to share that cherished moment with all our guests, no matter the circumstances on the day."

The couple — who first met in Las Vegas while Erin was in town for one of her brother's fights — also made other thoughtful accommodations for their son. With help from Total Sensory Solutions, they set up a sensory-friendly environment in his room at the venue, equipped with soft play and games from The Sensory Pod and TFH. "This gave him a place to retreat to whenever he needed a break, ensuring he could relax and recharge," Erin explains.

They also partnered with the Dublin-based disability services and support organization Stewarts Care to bring two therapy ponies to the wedding venue for Harry to ride. Harry's own therapy dog, an Irish Doodle named Kennedy, also accompanied him to provide companionship and comfort.

For all the children attending the nuptials, Terry and Erin offered an array of fun activities including a bounce castle and a bubble balloon house (provided by Plush Party Events), arts and crafts and ann outdoor movie screening.

Terry and Erin's custom five-tier ivory wedding cake, designed by Irina Rogachevskaya from Cakes in Dublin, featured red velvet, honey chocolate caramel, Raffaello (coconut-almond), raspberry and Oreo flavors. The towering confection, which was elegantly decorated with edible flowers and a large cascading bow, was set up outside on a perspex plinth decorated with flowers.

For the couple, entertaining their guests with music was a key priority throughout the celebration. During the cocktail hour, they were treated to a high-energy performance by the New Brass Kings, a six-piece acoustic band.

As the reception got underway, the Ambassador Band, a 10-piece group who flew in from the U.K., welcomed guests into the ballroom, performed during dinner and played Terry and Erin's first dance to "Unconditional" by Sinéad Harnett. The band later did another lively set after the fireworks display by Rocket Pyro went off in the sky.
