You're coming near the opening here is what you need to know...
- there is lines for everything. Food, store, both rides.. Only thing with almost no line is face painting becaus emost just walk past it and realizing it was a thing until they see someone face painted.
- for food,
mde app and order online to bypass that line.. You can't use dining plan with online ordering so it's a good time to make that a meal out of pocket and use your credits in another way during the trip like getting 3 snacks for each meal credit or a double table service credit location.
- FOP is the longest line so if your going to standby, na'vi will get you a little time back but only about 15-20 minutes of your time.. it's not a huge difference, don't change a fastpass unless you luck out and can modify the existing to get FOP.
- there might be a wait to get into pandora itself, but a fastpass will get you in faster, keep any fastpass you have.
- both rides are indoor, there is no difference to the experience for time of day.
- The store is a good 30-60 minute wait to get inside and you will not be running out quick if your getting a banshee, there will be another instore line for that..
- There is a good selection of clothing and other things available outside of pandora so maybe stop by the shops near the tree (both sides) and take a look in them for what they have and you might just skip the store entirely..
Other than that, I've just described all of pandora. It's not that large.
