Just my opinion here, but you really don’t need express. If the park opens at 9 AM, be at the gates at 7:45, you’ll be let into the park at 8:30 and can queue for the lower lot for the 9 AM open. Hit the rides in this order...
Mummy > JW > Transformers > (at 10:45 AM get a VQ spot for SLoP at 5 PM) > Simpsons > Studio Tour > HP > Hippogriff > Despicable Me > SLoP > Kung Fu Panda
I had time to hit everything including 3 meal/drink breaks with 20 min to spare before closing (Panda wasn’t open yet that day). You could probably fit Animal Actors in too since we spent a good hour drinking at JW and Duff Gardens.
