One other thing I noticed is that you don't get the Patrick Warburton safety video if you use FPs. At least we didn't last month, but then again, I think it was a slightly modified FP line because we were sharing it with the exit line. My family was slightly confused about the seat belts and the loop for "shorter aviators" since it wasn't explained to anyone before we entered the ride.
I think our taller aviators tried passing the seat belt through the loop too. If it wasn't uncomfortable, I guess it was okay. LOL!
