I took the advice of The Man in Seat 61 (who was also a great resource when I traveled Italy and Switzerland). He suggests using Loco2 as an easy alternative to Renfe, and I can see why. I'm looking at both sites side-by-side, though, and I don't understand why I'm seeing different times for Madrid to Granada on May 5. Loco2 does have a note on the site that recognizes the fact that the AVE goes to Antequera and they bus you the rest of the way to Granada (although the site will still show the MD train). The Renfe site shows AVE-Bus. But shouldn't the departure times be similar on both sites? Particularly if Loco2 is supposedly linked right to the Renfe site.
The prices are also quite different. Renfe shows as little as €27, while Loco2 shows about €64.
Is this a case of Loco2 being wrong, or Renfe being it's squirrelly self? And which to use to make sure I get a valid train ticket?
Also, on the Renfe site I see under the class listing "Turista con enlace." I understand the Turista, Turista+, and Preferente classes, but I can't find an explanation for this designation. Does that have to do with the change over to the bus?
