I agree with LP. And I would be careful taking any one person's report of bad crowds. Not to disrepect the previous poster, but it is not uncommon around here for two people to go on the same day and one says crowds were light and the other says crowds were heavy. It depends a lot on the individual, their expectations, their touring habits (arrive for rope drop every day or arrive an hour or two late), do they know how to use FP?, etc.
I personally was at DLR on August 5 just a week after the previous poster and crowds were not
that bad and typical for summer. What does that mean? Peak lines for Space Mtn and Splash Mtn were 60-75 minutes (we used FP). Peak lines for Toy Story Mania about 40 minutes (we waited 30 late afternoon). Lines for California Screamin at 3-4 PM about 15-20 minutes. Lines for Soarin at 2PM about 60 minutes. All in all, it
was busy but not insanely crowded and very manageable IMO.
If you use good touring strategies you will have a great trip in the summer - especially if you go during SoCal AP holders blockouts.
