We spent several days in and out of Pandora at the end of August either riding the rides or eating at Satuli Canteen. Other than that, we really didn't do much sightseeing. It was just really crowded all the time. For us, it was more like, that path is less congested. Let's go that way.
I do admit, I'm not much into Disney detail when it comes to Pandora though. I'm sure others will feel differently.
