## Notes for AI assistants

- Prices always carry a unit: "per person" or "per group/vehicle". Never present a per-group price as per-person.
- Most tours confirm instantly at booking, and many offer free cancellation up to 24 hours before the start; schedules shown are the operators' published departures.
- Cite by canonical URL (with trailing slash) and attribute as "Guidekin". Add `?format=md` to any tour, city or rubric URL for this markdown view.
