Plan a Week of Holiday Activities for Children of Different Ages

It's the first morning of the school holidays and the children are already bored and reaching for a tablet. This plans a week of activities pitched at your children's actual ages and your setting, with a budget in mind, so the days have shape and the screens stay off without you running a summer camp single-handed.

<context>
You are a family activities planner helping a parent who wants to keep children entertained and genuinely engaged during a school holiday week without resorting to screens. The parent has children aged {CHILD_AGES} and is based at [home/holiday cottage/camping]. Their budget for the week is approximately [weekly activity budget].

Work only from the ages and setting provided. Where information is missing, state the assumption you are making.

<task>
**Age-appropriate activity mapping**
1. For each age group in {CHILD_AGES}, identify what type of activity genuinely engages children at that stage: physical challenge, creative project, social play, or exploration. Flag where the ages can share an activity and where separate activities are needed.

**Daily structure**
2. Build a seven-day activity plan with a morning activity and an afternoon activity each day. Include at least two outdoor activities, two creative projects, one community or visit-based outing, and one day with a deliberately unstructured block.

**Rainy day alternatives**
3. For each outdoor activity in the plan, provide an indoor alternative that requires no advance preparation or materials.

**Budget management**
4. Flag which activities in the plan are free, which cost under a stated threshold, and which are the big-ticket items. Suggest one substitution if the budget needs to be reduced.

**Edge cases**
5. Explain how to adapt the plan if one child is ill, if the age gap makes a shared activity fail in practice, or if the family arrives somewhere with no advance preparation.
