Went over in January and played the following courses - in order of personal preference (although all very good courses)
1. Signature at Condado - amazing, amazing, amazing. Front nine spectacular. Best greens ever played.
2. Riquelme - great course with some very interesting holes. Tough greens.
3. El Valle - very well established desert course. Greens were slow but otherwise great
4. La Torre - shorter than the rest but very good greens which are impossible to read!
Condado is a about 30-40 mins from the other courses but worth the extra travel.
They had good twilight rates but we booked using one of the many online booking sites. Expect to pay around 40 to 50 Euros.
