When we went in September '04 my daughter had just turned 4. She LOVED IT! We sat her in the middle of her mom and me in the front seat so she could see and still "feel safe." She laughed and screamed at the same time! And she insisted on repeating it several times. She said this ride was way better than Splash Mountain--we coaxed her onto that ride, she started crying midway, laughed all the way down the hill, and started crying again at the bottom. When we got off she said she'd NEVER do that ride again. So we were quite suprised when she wanted to go on Test Track. We explained to her in a lot of detail what it was like, the different "test" areas you go through, the sudden lights, how it seems like you're going to crash through a wall, then the speed (still nothing like riding with daddy), and that there are no big drops, and she was good to go! Everyone knows their own kid best--just assure them it's safe, controlled, and fun, and let them see that in you while you ride.
