WildCat has a much lower capacity than Iron Dragon. I'm not so sure that Wildcat has more ridership, matter of fact, I would bet that it doesn't. While Iron Dragon is not a super thrill ride, I find it a nice, fun ride that is a great family ride. My friend's daughter loved the ride, she rode it about 10 times and is her favorite ride at CP. I find the back seat the most fun. You get a nice dropping sensation down the first hill and a lot of swinging action during the pretzel over the lagoon.
