Cary,
The Palms is either the second or third best desert course I have ever played (Behind only Shadow Creek and maybe Casacta). That written, do not look for any desert. I believe it to be Curly / Schmidt's best work. Other than that, PGA West is a blast to play once and I really liked Dye's CC of the Desert. One last note, the Palms is private, if that matters.
