Kellogg’s is re-launching its annual ‘Grown-ups Go Free’ promotion with Merlin Entertainments – this time with the £50 giveaway value on-pack.

Kicking off in the run up to Easter bank holiday and school breaks, the promotion will start in March 2017.

By using the voucher on promotional packs of Kellogg’s cereal, cereal bars, Nutri-Grain products, Squares and Fruit Winders, families can bag free tickets to top Merlin attractions such as Thorpe Park Resort, Warwick Castle and the Dungeons, saving up to £50.

Consumers simply cut out the voucher and take it along to the attraction of their choice. As long as they buy at least one full-price child or adult ticket, a second adult can also join the party and enjoy all the fun completely free.

Some 51 attractions are included in the promotion; all of Merlin’s UK attractions, including Chessington World of Adventures Resort, Sea Life Centres all around the country and the Blackpool Tower.

Kellogg’s sales director for the speciality channel, Nick Dawson, said: “Our annual Merlin partnership is the on-pack event of the year, which families are waiting for. We know consumers are expecting it and they actively hunt for it in stores in the run up to holiday periods.

“We hope this promotion will encourage retailers to stock up, ensuring consumers can collect their vouchers in their local store.”
