Played WC last year and was a bit disappointed. Having researched the course, I had huge expectations. For a top ranked course, I was expecting the practice facilities to be better, it's quite small and you can only hit long irons max. The practice green was undulating and too small considering the undulations The speed was not even close to the speed of the greens on the course. The course itself is quite spectacular, depending on the tee boxes, some tee shots are blind. The elevation changes are crazy, we started on the tenth hole, when we reached the 11th tee, we had zero idea how long it would play due 60-80ft drop. I wished I had slope on my range finder, it would have saved me several strokes during the round. It's a course you have to play a couple of times if you want to score well and I would definably go back and play it again. On a brag note, I ended up acing the 17th hole, had to buy beers for the rest of the night, but with my luck, we ended up at the casino for most of the night. Almost forgot, it's a slow round, don't be surprised if it takes 5 hours.
I really liked Coyote Springs, it is in the middle of absolutely nowhere. Agree with the OP that the clubhouse is minimal at best, I'm not looking for fine dining or a spa, as long it has cold beer and a half decent dog I'm ok with that. I understand that the course was suppose to be part of a bigger development that went bust. The course was in great shape, probably the best shape of all the courses on our trip. Wolf Creek, The Oasis, Sand Hollow, Paiute and Royal Links (starter was a dick!). The practice facilities was huge, wished I had more time there. Not a huge Nicklaus fan but really enjoyed the layout. I would definitely go back next time, even though it is a bit of a drive.
Have not played Cascata, don't know if I would drop the big coin there. I think there a two course deal with Rio Secco.
