Is this do-able? Seville to Madrid via ......

I have a few thoughts on this.

First, I don't think Cordoba warrants that much time (early Sunday morning until Tuesday night). Cordoba is a great stop, but unless you have some special reason to linger there, there's really no reason to spend more than half a day there. It's on the high-speed train line between Seville and Madrid, so you can actually do it as a day trip stop on the way between those two cities.

Second, you don't say how you plan to get around, but you should take a look at the map and transportation connections. To the point - Barcelona is a long way from every place else you're planning to go to. It doesn't make any sense to leave the "main" part of Spain (Andalucia, more or less), zoom off to Barcelona, then return back. Because of it's distance from every place else you're going, you should make Barcelona your first or last point in Spain - fly open-jaws so you don't wast a lot of time and money back-tracking.

That said, I would probably redistribute your time a bit - Madrid deserves at least as much time (possibly more) than any place else you're going, but you only give it one full day. And while Seville is nice, I certainly wouldn't plan for more than 4 full days there (especially given how your other days are allocated). Tastes vary, but to me, the way you have your days allocated are pretty inappropriate.

Hope that helps a bit.

thanks. i will edit and re post. less time in seville and cordova.
