The 39-room hotel, which is opening in June, will join the agency’s busy travel and hotel division, which already handles the PR for the Accor Group, including the Ibis, Novotel, Mercure and MGallery brands.
Mason Williams will be handling the hotel’s national PR campaign including press office, ambassador schemes, creative partnerships and launch party.
Louise Clark, managing director of Markerstudy Leisure, owner-operators of One Warwick Park, said: “We had seen some of the work produced by Mason Williams for other brands and knew we had to work with them.
“What really impressed us was their ability to get ‘in our skin’ immediately.”
Mason Williams founder and MD Rita Rowe said: “We are delighted to have joined the One Warwick Park team.”
“They’re dynamic, creative, passionate and have an exceptional eye for detail. Every element of the hotel has been carefully crafted and curated to ensure guests enjoy a superlative experience.”
