My buddy and I have been dying to check out Tyler, they have 5 courses (one park has 3 courses alone), so we might make a day of it.
I wouldn't advise trying to play all 5 in one day. Just spend the day at Lindsey, two sets of tee pads on both the red & blue courses. The gold course is one of the most difficult courses I've played so you can expect a very long round. The blue course is also very long and will give your arm a real workout from the long tees.
The Roc isn't too special. I'm glad I played it but have no plans on ever going again.
Havn't played UT Tyler, I hear that navigation can be an issue.
