Honeymooning in Spain Sept. 2 - Sept. 18.

Quick question. Without going into all the details of our trip, here's the situation: we have a hotel reserved in Madrid on the 3rd & 4th of Sept. and the 5th - 7th in Sevilla, planning to take the AVE in between. I thought we might be able to get the early train out of Madrid, stop and spend the day in Cordoba, then perhaps catch a train after dinner and continue to Sevilla for the night. Is this feasible? OR would you concentrate on Sevilla since we only have three nights there?

Thanks in advance. More questions to come
