Ten days gives Barcelona, Madrid and Seville two full sightseeing days each. Barcelona gets three nights because Gaudí, the old city and the sea pull in different directions. Madrid gets three nights for the museum district and neighbourhood life. Seville gets three nights for its palaces, cathedral and a separate day across the river. Each stop contains two full days; arrival and departure still take parts of the others. The worked calendar runs Monday 19 to Wednesday 28 October 2026, with trains on Thursday 22 and Sunday 25. It stays within the three cities, leaving rural Andalusia and northern Spain for another journey. The extra nights are useful for a settled base and a second kind of sightseeing, rather than a fourth hotel checkout.
