Dino Rama refers to the area of Animal Kingdom that was added to the existing Dinosaur area. The new rides are the Primeval Whirl and the Triceratops Spin. The area is themed really off the wall, it almost reminded me of Suess Landing at Islands of Adventure but toned down a bit.
As for Triceratops Spin, like others have said it is the standard Disney Dumbo ride. Nothing too exciting here. If the kids can do them at MK, they can do them here too.
Primeval Whirl is a twin Reverchon spinning wild mouse coaster. They built two of them because one would have not created enough capacity and would have caused long, slow moving lines. The two coasters are exactly identical except for the fact that they face in different directions. I definately recommend going to the right when the line splits as the ride basically overlooks the main midway and you can interact with the crowd while waiting to get pulled up the lift.
The ride itself has been Disney-fied over what Reverchon normally delivers to other parks. Theming aside, the spinning is not the intense, tilt-a-whirl type spinning found on rides like the Exterminator at Kennywood. Also the spinning doesnt even start until the middle of the ride. Many Reverchon mice start spinning once the ride drops off the lift or shortly thereafter.
As a coaster enthusiast I was very disappointed with the ride, however, I think that the ride is suited perfectly to Disney's target audience and was a great addition to the Animal Kingdom park. Perfect for kids and adults alike, this ride is a great one to share with family.
