Unless they're really timid, they should be fine. However, it's not an easy show to see. You have to get there early, and the crowds are so thick. It's a little easier with the dining package with reserved seating, but it's still not a cake walk. With kids that age, the overall package may make it not worth it. If you're giving up the chance to ride good rides, or a much-needed early night, or something else important, I'd skip it.
