The daughter of Prince Andrew and Sarah Ferguson was seen at Estelle Manor near Witney with her two-year-old daughter Sienna last June.
The venue at the former Eynsham Hall Hotel is set in 3,000 acres of parkland and accommodation can cost over £3,000 per night.
It has four restaurants, a 3,000 sq metre Roman-inspired bath house spa, 108 bedrooms and a gym with a class studio and padel courts.

There is also a shop, a kids’ club and a workspace.
A fellow guest told the Daily Mail at the time: “Within five minutes of arriving I was exchanging pleasantries with a friendly, very stylish and vaguely familiar young mother carrying her exhausted child.
“She turned out to be Princess Beatrice. Of course, she did – it’s that kind of place.”
Estelle Manor was among four hotels in Oxfordshire which were named as the best places to stay in the UK earlier this year.

The hotels are among 100 places named in the annual ‘Best Places to Stay in the UK’ list by The Times, which is put together by a team of ‘experienced reviewers’ who stay at ‘hundreds of properties’ across the country.
Ranked sixth, the spot was described as a “decadent Jacobean-style mansion” which is “fast becoming the Gleneagles of England”.
“The hotel’s distinctive look is a Miss Marple meets Gucci mash-up, with impressive public rooms draped in silks and velvets, and fine details lavished on its bedrooms, cabins and houses,” the article added.
