The couple married at Euridge Manor in Wiltshire on Saturday, with their two-year-old daughter Elsie one of three flower girls.
It emerged on Thursday that the luxury venue in Colerne has lost a planning dispute with Wiltshire Council and could face closure if it does not introduce measures to control noise.
The venue, which is owned by the founder of fashion chain Jigsaw, John Robinson, has been hosting weddings and events for several years, leading to complaints from neighbours about traffic and noise levels.
Euridge Manor now has 30 days to submit a new noise management plan, with The Times reporting that Whitehall’s wedding led to local residents objecting to loud noise, including “whooping and cheering, and amplified speeches”.
Horner’s post on Thursday included photos of the couple’s stay at Coworth Park in Ascot, Berkshire.
“After our fairytale weekend we started the week at @coworthpark,” she wrote.
“Elsie even got to meet a horse called Roxy! Thank you so much to the wonderful staff here.
“We feel full of love and will be back soon.”
Coworth Park is a luxury five-star hotel set in the “real English countryside”, according to its Instagram account.
One image showed the newlyweds’ hands together, displaying Horner’s new wedding ring.
Pictures of Elsie helping to lead a pony across a yard were also shared.

Horner and Whitehall, who is known for TV shows Fresh Meat and Bad Education, announced their engagement in December 2024.
Ahead of the ceremony, Whitehall, who was due to wear a Tom Ford suit, had a wardrobe malfunction and changed into a back-up Dunhill suit.
Speaking to British Vogue, Whitehall, 37, said: “I squatted down to pick up Elsie and my trousers split, my whole ass was hanging out.”
Meanwhile, Horner wore a strapless silk Galia Lahav gown and veil for the ceremony with Alaia Le Coeur heels, complete with a diamond necklace, earrings, bracelet and ring by Roxanne Assoulin.
She later changed into a second Lahav dress for the reception, paired with Freya Rose heels.
The 34-year old walked down the aisle with her father Perry and said that although she was really nervous before walking out, she later “got the giggles” because she kept tripping over her dress while walking up the stairs.
“Then Jack was blubbing at the end of the aisle,” she told British Vogue.
The lakeside ceremony included a Shakespearean sonnet performed by actor – and Whitehall and his father’s good friend – Neil Stuke, before the couple shared their first dance together to Michael Jackson’s Rock With You, with the party going on into the early hours of the morning.
The newlyweds are due to head to Venice for their honeymoon, with a stay on the luxury Belmond Venice Simplon-Orient-Express train.
