Yes, I absolutely expect crowds to surge after 8/19. We‘ll be going at the beginning of August though (July 30 through Aug 2, with Aug 3 being our pool/Downtown Disney day). I‘m currently logging wait times hourly for the weekdays we‘re planning to go to get a better idea of the crowd trends between now and then (I love numbers and statistics—I love doing the research leading up to our trips). I did notice that it’s NOT as mellow as it was just a few weeks ago. Today, for example, California Adventure was downright busy.
I‘ll see what I find out and will report back!
