Attractions include Cadbury World, a Harry Potter studio tour, Disneyland Paris and lakeside apartments in Italy. Each holiday comes with an age recommendation and details of tickets and excursions.

UK packages feature coach travel, while European attractions come with regional flight and rail options.

Jane Atkins, Shearings managing director, said: “This programme is focused on attracting multi-generational customers and features short breaks and holidays the whole family will enjoy… and will allow [core customers] to take their children and grandchildren away with a brand they know and trust.”

Agents will receive brochures in the coming weeks and Shearings’ agent toolkit (shearings.com/toolkit) has been updated with promotional resources.
