My dd did it when she was 5 and absolutely loved it. We're going back in Oct., this time with her cousin, and they're both going! My Mom said the same thing, but I didn't have any concerns at all. If there was ever a problem with it, I'm sure Disney would cancel the whole program right away. When my dd went, there were only about 16-18 kids (one of whom was a DISer's dd, who wound up being my dd's "buddy" for the day, that was really neat), and there were 3 adults, all of them female. When my dd came back my Mom asked her about it, and she told her she had a great time.
