There this past week and didn't use Express or have the onsite priviledges and saw everything in both parks. Wait times were mostly around 5-10 minutes. My son went on Hulk at park opening and they were sending cars up not completely full. Spiderman was basically a walk on. Dueling Dragons was a 5 minute wait. All the rides weren't crowded at all. The longest we waited was 30 minutes for Men in Black, which was definatley worth the wait in my opinion. This was my favorite ride.
In Studios we walked in Shrek at park opening, Jimmy Neutron was 15 minutes and majority of the other rides were walk ons. Jaws was about a 20 minute wait.
We arrived around 8:30 a.m. each morn and stayed until around 3:00. It took Mon (IOA) Tues (Studios) and Wed (combo of both parks) and we saw EVERY show, and did every ride. Crowds were really at a minimum. We have photos were there are about three people in the background. Made for a very nice time.
Studios was more crowded than IOA all days.
