The campaign is the latest work by the Japanese car manufacturer to target parents as well as their children.
The event, which takes place across its dealerships on July 30 and 31, will promote the marque's range of family cars, including its FR-V, CR-V and Civic models.
Created by DM agency Hicklin Slade, the direct mail pack is being sent to 70,000 families. Honda has used its database of prospective customers and its dealers' own databases to select its target audience.
The theme of the mailer is based on a children's party invitation. The agency has also designed a point-of-sale poster for use across Honda dealerships.
The Honda Family Weekend, which has been timed to coincide with children's school holidays, will provide entertainment for kids and the opportunity for parents to test-drive its family cars.
Upon arrival at a dealership, children will be given a goody-bag which will include sing-a-long CDs and DVDs. For every test-drive Honda will make a 拢5 donation to the Yummy Mummy Appeal.
Every family that attends the event will be entered into a competition to win an FR-V.
Lee Ann Crossley, Honda UK prospect relationship executive, said: "This is a perfect campaign for Honda to be involved with. Not only will Honda be communicating effectively with its target audience, more importantly it will be contributing to the CLIC charity."
The Yummy Mummy Appeal is supported by a number of celebrity mothers, including Davina McCall, Fern Britton and Lorraine Kelly.
In December last year, Honda targeted children with a series of brochures that were designed to appeal to children. Advertising agency Nexus/H created the brochure in two parts, one for four to seven-year-olds, the other for 10-year-olds.
