We were there 8/2-8/5 (Thursday-Sunday) Did SWO Thursday and part of Friday. We then hit IOA/US in late afternoon and evening. I went back and forth all three days. Stayed at PBH so we had all day express pass. Don't forget you get better seats at shows if you show your room key. I forgot that at several shows, but it really didn't matter.
It was wonderful!!! However at certain times of the day, the single rider line was than 10 minutes and the express line was 10-15 minutes so the single rider line was faster at times (especially Hulk and MIB).
I did notice a difference in the line time from last year. With that great room key last year we never had a wait more than 2-5 minutes but now with more people having access to the express lines, there were lines of 10-20 minutes which still can't be beat. I think it is great that amusements parks have come up with a system that allows everyone a chance to not have to wait in line for hours. I just don't know why more people don't use those passes.
There were more people there in August this year than last year when we went in October but it wasn't bad. Early morning and later afternoon was a little less crowded.
