The agency will run a press office for the mobile homes and family camping company, which owns and operates holiday parks in Southport, Preston and Cumbria.
Activities will focus on creative storytelling to drive engagement in the media and holiday social media space, as well as press trips and late deals.
George Harrison, of Harrison Holidays, said: “We look forward to seeing what they can do to raise the profile of Harrison Holidays and get our current and potential customers engaging with us in the ever important social media space.”
The account will be managed by Daisy Whitehouse, consultant account director Victoria Barker and Pippa Nixon.
The agency’s current leisure clients include Legoland Discovery Centre and the Sea Life Centre, set to launch in June at the Intu Trafford Centre.
