I would skip AK (we are doing half day). MGM has tons of stuff for kids that afe. Playhouse Disney, Voyage of the Mermaid, Beauty and the Beast, Honey I Shrunk the Kids Playground, High School Musical Pep Rally, Lights, Camera, Action Stunt Show, Indiana Jones Stunt Show, Muppet Vision 3-D, plus Fantasmic and Osbourne Family Specticle of Lights when you will be there. They will love it. You could also do a half day of AK and half day of MGM, and hit what would be your highpoints at each.
