Andalucía itinerary advice?
 

I am finalizing our itinerary for our trip in late April/early May. After spending 5 nights in Barcelona, we will be taking the train to Madrid and staying there for 3 nights with a possible day trip to Toledo. From Madrid, we plan to visit the following places but are not sure what order is optimal for train/bus travel:
Cordoba 2 nights
Granada 3 nights
Malaga 3 nights
Ronda 1 night
Sevilla 5 nights
We are flying home from Sevilla.
Any suggestions on the best order to visit Cordoba/Granada/Malaga/Ronda? Thanks!
