There's a current (last 3 year) issue with crowd calendars for Disneyland.... With the addition of CarsLand in 2012, there's not a lot of historical data on what to expect anymore. We can give general guesses based on national and local holidays, days off from local schools, promotions going on in the park, etc., but they can't account much for CarsLand drawing people in. That being said, CarsLand isn't the draw that it used to be when it first opened. What days are you looking at? I may be able to help you figure out what the crowds are likely to be like.
