How many people make up a "Family" Merlin Annual Pass?

A family pass is for a minimum of 3 individuals, with a maximum of 3 individuals over the age of 12 years. For example if you are purchasing a family of 4 you are able to have a maximum of 3 adults and one child under the age of 12. You can have a mixture that will suit your family needs.

We hope this answers your question.
