JoyL--I would suggest calling Carnival directly and asking them. Then you will know what the exact policy is. This way also whatever is said on this post will not matter since people have a tendency to give opinions instead of facts.
To answer your question--I don't think it is stating that you have to be 13 to use the children's pool, just that anyone under 13 needs to be with an adult. Which is a very good safety idea.
