What is the definition of a 'family'?

In order to select ‘family’ on a Direct Travel Insurance policy, the party must include up to two adults and any number of children aged under 18.

Please note: children can travel independently from the other travellers on an Annual Multi-Trip policy. However, the policy must be purchased by an adult who has responsibility for the child, and the child must also be travelling with a responsible adult at all times (such as a relative, guardian, or school teacher).
