Parks should be manageable (especially USF).
I recommend rope-dropping (if you have EPA) Hagrid > Velocicoaster > Forbidden Journey > anything else you want to prioritize at IOA before heading to USF.
Outside of Gringotts, USF's attractions thankfully have an average wait of 30-45, rare to see anything significantly over 45 on an average day.
Unless you're dead set on doing everything, I don't think Express is necessary.
