We just went in Sept with my 3 yo DS. He loved Buzz- that was his favorite! It's not scary at all. We rode it at least 10 times, too! In Fantasy land, he rode all the ride with no problem. The only one I was worried about was Snow White, but I sat with him and played a game to catch the witch before she caught us and it was no big deal. I t hink he fed off my vibes, so as long as I was upbeat and OK, he was too. My DS was too short for dinosaur! in AK, but I'm glad since it would have been too much for him. Way too bumpy. We will be back in December and I'm not sure I'll let him ride it then, either. He loves dinos, but we'll just have to see. Feel free to PM me or post more questions for that age since we just went. Three is a great age for Disney!
