## 📊 Key Concepts

### Density Score
A metric that combines distance, time, and place count to measure trip complexity.
- **Formula**: `(distance_km × 5 + time_hours × 10) ÷ place_count`
- **Range**: 0-100+ (typically 10-60 for real trips)
- **Purpose**: Objective measure of trip complexity

### Density Levels
- **Low** (<20): Easy self-planning
- **Moderate** (20-35): Tour optional
- **High** (35-50): Tour recommended
- **Very High** (≥50): Tour highly recommended

### Decision Factors
Multiple factors that influence the recommendation:
1. Density score (primary)
2. Total distance
3. Time commitment
4. Group size
5. Place count
6. Activity type

### Debug Info
Comprehensive information explaining the recommendation:
- Daily metrics for each day
- Overall trip metrics
- Decision factors with reasoning
- Recommendation explanation
