Have you been out that way lately? The beaches around there are fabulous and hardly ever crowded, and the restaurant at the resort, though a bit overpriced IMO, serves some pretty decent food.
Someday that development (full name: La Jolla de Cortés) is going to be a whole new town. I'm ambivalent about that, particularly because of the environmental aspect. But it's a magnificent location, there's no question about that!
