Matt:
Rio Seco has a wonderful location -- provides stunning glimpses of the Las Vegas skyline and has faciltiies with all the bells and whistles including a stellar teaching area.
However ...
The course is a pro forma Rees Jones layout. Nothing really bad per se but I would not recommend it on a short list of fun and compelling architectural layouts.
Rio Seco, along with Cascata and even Shadow Creek -- are courses that would certainly be joined together because like Vegas, at least to its detractors, it's more about the surface than any serious depth.
