Well you messed up bad at Universal by only getting on that many rides with Express Pass.....
You could have done that many in the first 4 hours of the day
It was an extremely busy day at Universal. if you ask any of the team members, they always tell you Express pass will be about half the regular standby wait time. It was usually more like a third or a quarter of that time, and a few times it was a walk on. When the standby line is 90-120 minutes for the big rides... wait times in express are easily 20 minutes and sometimes get up to 30+.
20-30 minute waits for Ollivanders (no express pass), Forbidden journey (x2), flight of the Hippogriff, Hogwarts express, Spiderman, Hulk, high in the sky (surprisingly), Gringotts, and Simpsons. So right there is ~4 of my park hours just in line for these rides.
Probably about 5-10 minutes for: Jurassic park, cat in the hat, men in black, ET, and despicable me. Lets call this about 45 minutes in line/walking through the lines.
Hagrid's was a 70 minute wait. No express for that, and we actually hit it when it was much lower than most of the day.
So total time in line= ~6 hours of my 9.5 hours were spent in line even with express pass.
Actual Attraction time:
Ollivanders 5 minutes, Journey (x2) 4 mins, hippogriff 1 min, Hogwarts express 4 minutes, Spiderman 5 minutes, Hulk 2 mins, high in the sky 5 minutes, Gringotts 5 minutes, men in black 4 minutes, Simpsons 4.5 minutes, Jurassic 7 minutes, cat in the hat 6 minutes, ET4.5 minutes, despicable me 8 minutes, Hagrid's 3 minutes
Total time spent on rides= 72 minutes
Total time spent in line or on rides= ~7.2 hours out of my 9.5 hours.
So I spent about 2 hours and 20 minutes "wasting" my time that day going in a lot of the stores, doing wand magic, taking pictures, using the bathroom, getting some food booth snacks, and walking between attractions.
Could I have done better? Probably by planning out better times to hit harry potter and marvel lands, however the whole point of express to me is to just jump in the line if you are by the ride you see. I also could have shopped or did wand magic a lot less and hit more rides, but that's part of the theme park experience to me. I spent a lot of time in stores at magic kingdom.
I was also in universal the next day and the crowd difference in both standby and express was noticeably different, almost everything was only a 5-10 minute wait in express when the day before. I only spent from 8-3 in the parks that day (we were driving to the beach) and hit 11 rides in those 7 hours, but waited for both hagrides and velocicoaster.
