De Vere Venues has won a management contract to run East Sussex National, a hotel, meetings, events and golf complex.
The hotel at East Sussex National has more than 100 bedrooms, as well as conference and meeting capacity for between eight and 400 delegates, across 10 spaces.
The venue sits in 1,110 acres, and its two Championship golf courses have staged European Open events and played host to the likes of Nick Faldo and Colin Montgomery.
Tony Dangerfield, chief of De Vere Venues said: "East Sussex National is a real asset to De Vere Venues expanding property portfolio and we're delighted to welcome them on board. The facilities, including the championship golf courses are second to none and we're looking forward to welcoming delegates through the doors."
Michael Hunt, the owner of East Sussex National, said: "De Vere were chosen ahead of other candidates because of their flexibility in adapting their requirements to suit the existing culture of each individual hotel and their emphasis on staff training and customer satisfaction."
Other venues to have joined De Vere in the past six months include: Heythrop Park, Chicheley Hall, Kassam Stadium, Studley Castle and Altitude London.
