Our trip to Spain

Now that the holidays are almost over, it’s time to plan a trip to Spain in the fall. This will be our first holiday after we retire, and our third to Europe, travelling with the same friends. I’ve started to study some Spanish, putting Italian on hold for the time being. Our tentative plan is to fly into Madrid, fly on to Granada, take the train to Seville and then meet our friends in Ronda. The flights will be easy to arrange. Air Transat flies open jaw into Madrid and out of Malaga. The train is another story.
Rick Steves has a very helpful brochure on trains in Europe which is available as a pdf download, but even with its help I remain confused about taking a train from Granada to Ronda or Seville. http://www.ricksteves.com/rail09/pdfs/09_RailGuide.pdf
I have just now found some helpful information about the white villages of Spain.
