I was there this morning, and didn't really have a good experience. I was parked and in line with my ticket by around 7:30, which I admit was kind of late. But my goal for the day was just to get in and see Hogwarts and have a butterbeer.
From Citywalk, we were directed, to the right, to a line that started at IOA and went down by the Studios, where we ended up waiting. After it snaked around back to Citywalk and they started letting people in we noticed that there was now a second line that was allowed to go to the left from Citywalkt, and they were letting people in from that line before us. We had been waiting for over an hour at that point.
Once in the park, Universal employees directed us to the right towards Suess Landing if we wanted to see Harry Potter. After being turned back around the Lost Continent area we ended up in a line in Suess Landing and were told that after the line on the other side of the park was let in to HP we would be let in - estimated 6-8 hour wait. We decided to stay.
After waiting in Suess Landing for maybe 1 1/2 hours the word started to be passed through the line that we were actually not in a line at all and would not be let into HP. No employee ever came down the line to tell us anything. But the employees that had been keeping us in line were now gone. Eventually we got to the front of the line as security closed the gate right in from of us and blocked the way over to the Lost Continent.
All we were told is to go wait in the other line, which would be at least an 8 hour wait or go to guest services and complain, and that was only when people corned Universal employees. There were loads of unhappy people. And really upset, crying teenage girls. We went to guest services from there, and the line for that was over an hour, and we made it before it was too long.
