Cordoba??? Sounds like its some where you want to visit, Just do it. It will be better then another day in Madrid trust me.

Yeah, probably a little too ambitious, but what the hell, go for it.  My one real criticism is that you should add another day in Barcelona.  Much of that first day will be lost getting your luggage, to the city from the airport, being really tired etc.

I would also add a day to Barcelona. I would consider going out to Segovia from Madrid. I was just there about two weeks ago and absolutely loved it. It’s about an 1 1/2 hours by bus and definetly worth it.

While Madrid is large, it’s not the most interesting city in Spain. If you would like to keep your itin. this ambitions, I would suggest dropping a day in Madrid and adding it to another city.  

I’d suggest a minimum 3 days in Barca, lots to see & do there.  I’d also skip granada & madrid and maybe visit a Portugese city, I found Portugal much more charming than Spain & it’d be a nice contrast for you. My $.02

I really want to get to Portugal some day.
But a guy who likes museums probably would not want to miss the Prado, the Sofia or others.

Granada is a great place, I liked it better than Sevilla. But Sevilla has much more in the way of sightseeing, while Granada is more focused on nightlife (apart from the Alhambra).

Hi
 
It’s a little rushed but doable.  I must say that I’m a huge fan of Madrid.  I would cut my time in Barcelona if I had to squeeze more time into this city.  Granada is awesome – stay in the atmospheric Albaicin area.  Cordoba is interesting enough but one day is enough if your schedule is tight.  Another terrifc day trip out of Madrid is a visit to beautiful Toledo.  Segovia is nice but if I had to choose, Toledo would be my preference.  To save time but at a little more expense use the high speed trains (AVE). Madrid to Seville in 2.5 hours and Seville to Cordoba in 40 minutes.  Whatever you do in Spain, it’s all good!

[=“times new roman”]When in Barcelona, spend a day out at Montserat, Montserat is a monastery perched on a cliff top. It takes an hour by local train from Barcelona. From the station you take a funicular up to the Monastery. Walk around the Pilgrimage trails, before heading into the Bascillica, make sure you are there for the 1pm blessing, the choir boys even come out and sing. Highly recommend this[/]

As others have already mentioned, I’ d say more time in Barcelona. Wicked city and really popular at the moment. Theres loads to see. I spent a weekend there, (3 full days) and it wasn’t long enough, on the bus on the way back to the airport I saw so many things that I wished I’d explored but didn’t have time. Having said this, I expect you could find loads to see and do in all the places you’ve mentioned. Maybe you should extend your stay by a week??? []

March 19 is San José, celebrated throughout the Comunitat de Valencia with things like las Fallas de Valencia.  You’ll be so close …
