Generate a Family Activity Plan for a Week of School Holidays

The holidays stretch ahead and you can already hear the I'm bored by Tuesday. This builds a week's plan for your children's ages and your budget: one main activity a day, balanced with stretches that do not need you running the entertainment. For parents and carers who want the week to flow without being the full-time event coordinator.

<task>
**Generate a week activity plan by:**
1. Providing one main outing or activity per day that suits the children's ages
2. Balancing active days with quieter days to prevent exhaustion
3. Including at least two low-cost or free activities
4. Adding a rainy-day backup for any outdoor plans
5. Noting one activity the children can partly self-organise without adult direction

If the children have specific interests (sport, art, animals, making things), include these.

- Day-by-day plan: Monday to Friday, each with a main activity, estimated cost, and a rainy-day alternative
- Weekend bonus: one easy weekend activity for families who want to continue the momentum
- Tone: practical and realistic; not every day needs to be a highlight
