Cadbury is partnering with Merlin Entertainments to offer two-for-one entry to UK attractions in an on-pack promotion.

Running across its chocolate bags and multipacks, the £1m promotion includes offers on Legoland Windsor Resort, Thorpe Park, Chessington and Alton Towers.

The promotion will be backed by PR and social media activity.

Other food brands to partner with Merlin Entertainments this year include Branston Beans and Kellogg’s.
