Oh my goodness, yes, I have always been envious of that gigantic library in Beauty and the Beast. The walls covered in books a few stories high... or hundreds of stories high depending on how you look at it ;3
My favorite was always Cinderella, though, and... I'm not sure why, really, lol.
But I did always want to be Peter Pan. Something is really fun about never growing up and getting to fly around. Funny thing is, though, I don't think I've ever actually watched the movie. I've just watched Hook a million times. Robin Williams was absolutely perfect for a grown up Peter, so boyish and silly.
