Beauty and the Beast and Finding Nemo are my favorite Disney movies. I also like 101 Dalmations (the various versions) and the Muppet's Christmas Carol. My favorite Disney characters are Mickey, Minnie, Pluto, Dory and Belle.
My favorite Disney songs are actually the soundtracks from the parks (Wishes, Holiday Wishes, Fantasmic, Spectromagic, etc.) but I also love You Can Fly!, Beauty and the Beast, A Whole New World, and Just Around the Riverbend.
