I wouldn't try them back to back. Either rope drop or FP+ FOP in the morning. Return to Pandora in the evening after ROL for Navi River. Again, my wait was 5 minutes.
If you have an ADR for 10:30 or later, I would just do FOP first thing, walk to Africa, take in the first show of FOTLK at 10am (the show is 30 min), then check in for your ADR at TH.
I think that would cut down on the stress level to book it to TH after Navi River. Instead 30 minutes to chill out and enjoy a show then check in for your meal.
