DO NOT GO TO DAK ON EMH DAY. That will mean the park will be more crowded than usual. Always pick a park w/o EMH (except DHS due to SW:GE).
You probably won't get a FP+ to FoP as it is so popular. So, at rope drop go to FoP, could be an hour wait. It takes like 5-10 minutes to walk from the entrance.
Then your first FP+ should be Na'vi River Journey. Try for 1-2 hours after rope drop.
All FP+ should be early in the morning, unless you pick Safari for say 4 PM. Once you use all 3 you can select more. That being said, I think at DAK it is more important to get Safari in the afternoon as there are very few other rides that require FP in DAK outside of FoP.
