You can play Cedar Hill for $35 year round, Cordova Bay is $69 fall/spring $89 summer.
Cedar hill is more a course for beginners and seniors, serious golfers would indeed pay the more expensive rates for a regulation course.
I wouldn't consider myself a beginner nor senior, and I still play Cedar Hill sometimes. You obviously can't beat $35 for a round.
The problem for Cedar Hill a few years ago was the extraordinary wait times because no reservations were allowed. I remember going on a weekend morning, putting our names down for a foursome, then going to what is now Brannigans (used to be O'Donells I think?) for breakfast and coming back and still waiting. And when you did finally get on the course, your round took 5+ hours. But the course was always packed.
I'm not sure why, or if it is solely due to the fact that you can make reservations now, but last summer I was pretty much able to walk onto the course at almost any time of the day for a round, and was done in under 4 hours a few times.
