If your child is most excited about meeting tons of characters at Disney, know that means you'll also be waiting in tons of lines. You can FastPass some characters experiences, including Mickey Mouse, Ariel, and Cinderella at the Magic Kingdom, but also consider character dining experiences (Chef Mickey's at the Contemporary Resort is a good one for meeting Mickey, Minnie, Donald, Goofy, and Pluto) to knock out a bunch of characters at once.
