The pleasure of this route is the change in scale: Seville’s immense cathedral, Córdoba’s forest of columns, Granada’s palace courtyards and then Málaga’s open waterfront. You get one full sightseeing day in each of the two longer bases. Córdoba fits between them without returning to Seville, while Málaga gives the journey a different ending. This is a city holiday with three hotel changes.
Arrival and departure count as days one and seven. A Monday start gives Tuesday in Seville, Wednesday in Córdoba, Thursday into Granada, Friday at the Alhambra and Saturday into Málaga. Shift the monument bookings to their actual visitor calendars when using other dates. An early final flight leaves Málaga with only an arrival afternoon; put the fortress there or extend the trip.
Keep Cádiz, Ronda and the white villages for another journey. Adding them here takes time from the four cities and brings another transfer. If one stop is already familiar, fewer bases and longer stays are a better use of the same week.
