Renaissance is a very good course. I was a member there until last year after I did the math and realized I was only playing about 15 rounds a year. Amazing practice facilities, and a course that grows on you the more you play it. It has steadily improved since it opened. In its first few years, Renaissance was way too penal, with deep fescue everywhere. It looked awesome but was too difficult for the average golfer. They've also widened 7 considerably and improved the drainage, making it more playable. I liked the 4th with all the trees obscuring the view of the green (but not in play unless you top your tee shot), but too many members were losing balls from topping their tee shots. It's still a good hole with the changes, just less intimidating now. The 18th is really the only hole that I don't like, and that's only because of where it falls in the round.
The bee hive of bunkers on #2 at Red Tail really isn't in play. It's more of a visual aid to give you an idea of where the dog leg is on the par 5, since the turn to the right is obscured by trees. It's sort of an extravagant and unnecessary feature, in my opinion.
