There are a thousand reasons to love Andalucia. I lived there for three years from '91-'94, and the climate, Mediterranean beaches, fiestas, wine, cuisine, history, architecture, landscape, language and seņoritas all came together to create the most enjoyable experience. So what if they don't have a Doak course (no disrespect to Tom, who would be a welcome addition to Iberian golf).
From the photos, Valderrama hasn't changed since I was last there to see the Rdyer Cup in '97. A solid if not brilliant course, with an intelligent routing and variation in holes. I played it twice, rode it with the owner Jaime Patiņo once, and spectated at a couple of pro tournaments. If it means anything, fourteen years later I still clearly recall every hole.
Valderrama conditioning sets the bar for European golf, and there are some terrific views of Gibraltar and the Med. I adore the cork oaks, which bring to mind the fine bottles of Rioja. Don't leave without trying the pata negra cured ham.
For what it's worth, I also played El Saler, and while the links holes along the Med coast are a novelty, the inland holes, about half the course, are most forgettable, and the conditioning, when I was there in 2000, was disappointing. Valencia is a nice enough town and region, but it lacks the grace and sparkle of Andalucia.
Of course, that's only one man's opinion, and I may be wrong, but I doubt it.
