I visited this place during our stop-over in Abu Dhabi last month. It was a quite pleasant experience, especially for me and my son, as both of us love sports car, with Ferrari definitely is included. So it was a treat for us to look at the historic and latest Ferrari cars showcased in this mega indoor park.
On attractions, other than the 2 roller coasters, the rides are average. But I would say Fiorano GT roller coaster is among the best ride I've ever taken, simply because it doesn't take you to dizzying height, which for people afraid of height like me, it's really a treat. But boy, it is fast! And the idea of chicane-like track is very welcome, and fitting to Ferrari's theme.
Other than that, the Test Driver dream is okay, it does give you sense of speed in riding F1. I lined up for F1 simulator, but when it came to my time, it was broken. Too bad.
I would say, for you who love fast car (and Ferraris), it's worth to try for first time. Am I going to visit it for second time? Maybe not.
