I played there just last month-
First off, it is a very high end development behind beautiful gates with very expensive housing. The clubhouse and practice facility are terrific. The original 18 holes is exquisitely manicured and has some pretty par 3's. Quality wise, the course is disappointing. OK, really it's not very good at all. The new course I think has more potential- it's more desert like with a lot of transition zones.
I certainly wouldn't go out of my way to play Toscana.
