My daughter absolutely loves any kind of thrill ride that she will be able to go on. However, even though she does love these things, I am a little afraid of safety issues with her being only 3 years old. She's just a tall girl that's sort of a tom-boy. Was wondering what you all think about her going on the Slinky Dog Dash (especially)? However, she still has three months to grow before our trip and I am wondering if she will be tall enough to Fastpass Splash Mountain too? Advice, please? I know that she will want to go on these rides if they are safe enough at her height, but if she is exactly 40inches on our trip will CM's let her on the ride with a Fastpass? Just not sure what to do.
