Might not be a concern of yours, but I went to Disneyland 4 years ago and found that this was extremely useful in terms of figuring out how to minimize wait times, which rides you can actually obtain more than one FASTPASS at a time for (and when to get them), etc. Got the 90-day one for $15. Money well spent.
I only went for one day though so it was in my interest to maximize my time spent there.
