Spain

So much passion the buildings melted

The Alhambra, Gaudí, Calatrava. A nation with too much passion to build in straight lines. Tapas and pintxos make it enjoyable even on a shoestring.

Getting around: Barcelona, Andalusia and the Basque Country are far apart. Group your visits by region to spend less time in transit.
Exploring: Book timed-entry visits first, then fit exterior visits and walks around them.
