Re: My visit to Seville in 2013
you will need one day to just visit the palace in Granada. The small city is very good place to visit. In my view Granada should be a prioriy with more than one day.
Other option is to consider Cordoba, you can visit it for half a day from Seville. There are three places, mosque, a roman bridge near mosque and a castle which you can skip. All these places are reachable on foot from train station.
