Yup. World. Very manageable. For all the parks during a four-day stay I don't think we waited over 60 minutes to get on any ride. It was only really crowded during the fireworks show at night at Magic Kingdom. I've been there before during the months of Jun-Aug and the crowd and wait times have been unbearable.
Im going in late August, hopefully the crowds aren't too crazy. Did you happen to see how the lines were for Anna and Elsa at the MK? Im going with 4 girls under the age of 6 and thats kind of a big deal.
