Pros:
My have-to stop any time I find myself in Vegas. OB is used very effectively to keep the course technical and challenging, but they still let you throw a few over them mountains.
Lots of great, memorable holes on the front 9, starting with number 1's tree hallway.
Cons:
The back 9 feels a bit tacked on. While the front 9 is extremely creative and fun, the back 9 really feels like just what it is... a large perimeter of leftward leaning courses going around the rest of the park. Don't go right or you'll go into the road, don't go extreme left or you'll hit families having a day at the park.
Additionally, signs with a bit more effort wouldn't be a bad idea. It's really hard to tell where exactly stuff is with satellite pictures, and the tee layout can be hard to figure out at times.
Other Thoughts:
If you don't know, the wind blows in Vegas. Don't be surprised if you find yourself playing a technical course in 20 mph winds and suffer accordingly.
