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. It is a city holiday with three changes of hotel, rather than a survey of all Andalusia.
Count the arrival and departure as days one and seven. A Monday arrival produces a useful worked pattern: Tuesday in Seville, Wednesday in Córdoba, Thursday into Granada, Friday at the Alhambra and Saturday into Málaga. Other start days also work, but move attraction bookings to match their calendars. The sequence assumes a Seville arrival early enough to settle in and a Málaga departure late enough for a short final visit; see the last-day alternative below if your flights remove either window.
Cádiz, Ronda and the white villages deserve their own time. Adding them here costs an existing city night or introduces another transfer. For a first visit, keeping this four-stop line makes it easier to recognise what you have actually seen: a palace garden, a neighbourhood beyond the main monument and an evening without a suitcase. If you have already visited one of the cities, reduce the number of bases and give the saved night to your favourite stop.
