Clareville, a London Public Relations and Communications consultant, and Social Media Chefs, led by social media expert Miguel Neves, have partnered to offer a "comprehensive and coordinated service" to destinations, venues, hotels and event technology experts, a press release reads.
These three new routes will begin in April next year.
