My plan for 11/19 is hit USF for EE – Gringotts x2, then Olivanders then take the train to IOA for 9am opening and hit FJ, then Kong, back to the Wizarding World for Dueling Dragons and Flight of Hippogriff and Frog Choir. Then take the train back to USF for Diagon Alley, lunch and then USF attractions as we see fit. Basically, first day am will be all Harry Potter plus Kong. Afternoon at USF will be other headliner rides using hotel express pass.
When we enter IOA via Hogwarts train, I will probably check the Universal Orlando app to check wait times for Kong vs FJ and may change the order - hit Kong first and then return to FJ and rest of the Wizarding World
