Hi Lisa!
I just returned home from a trip to
Pandora - The World of Avatar in Disney's Animal Kingdom Theme Park, and I'm still dreaming of Flight of Passage and
Satu'li Canteen.
If you driving your own car, then I would say that schedule is doable. If you are relying on Disney transportation, then it would be extremely tight, and I don't think it's worth the stress. Driving time from Disney's Animal Kingdom to Disney's Polynesian Village is probably around 20 minutes. If you are using Walt Disney World Resort buses, then you also have to factor in the time waiting for a bus. You could get lucky or you may just miss one and have to wait for the next bus. They run approximately every 20 minutes.
I suggest trying to reschedule your 'Ohana breakfast to a day when you're at Magic Kingdom Park. If that's not an option, then I recommend arriving at Disney's Animal Kingdom Theme Park at least 45 minutes before park opening, and you should be able to ride Flight of Passage and Na'vi River Journey before you have to leave for 'Ohana. The earlier you arrive, the further ahead you are of the rest of the crowds.
Good luck and Sivako!
