Been at least 7 years now, but played it a few times before it went private and once with a buddy who was staying in Watercolor. Given other prices in the area, i'd assume its well north of $150
Since you are a member of a private club, you can join Thousand Greens, a network of private club members. You can then submit a request to play Camp Creek. If a member accepts your request they will upholstered you. Go to thousand greens.com. It costs $60 per year. It's a wonderful network. I've met many good folks, most passionate about golf, this way.
Yes Raven is always super busy. We booked it over six weeks out and we're only able to get a 2:30 tee time. It's a nice track though. Played super tough the day we played. Not sure if it was the north wind or what but it ate our lunch. We played it the previous year and I didn't remember it being that hard.
