Mark,
My understanding is that the routing of the course is still the original, with the exception of par-3 9th hole, which was moved back to allow for more hotel rooms.
Flat property, with two beachside holes with sandy soil, but no dunes, however. I would say few excellent holes (1, 4, 5, 18) and the rest quite monotonous. Weak par 3s. They have recently added a couple of ridiculous ponds in holes 3 and 8. Greens don't have much character, but I don't know if they are original or have been altered over time.
The first nine are fun, with a good set of par 4s, both long and short. The second nine are more boring with just a couple of worthy holes.
Maintenance standard is quite poor, as the course is managed by the same hotel chain (state owned) that manages El Saler in Valencia.
Although the course is probably not one of Simpson's great designs, still much fun and much better than most in Costa del Sol.
Regards,
