Flying into Andalucia tomorrow, got a car hired and first night booked. There for a week. Where should I go? What should I do?

Want to see Granada (Alhambra in particular) & Seville. Cordoba, Cadiz & Ronda seem worth a visit too. Is Gibraltar worth going to, or just a rock?

No need for any Pixies jokes, but feel free if you really need to make one.
