Are there some lines you can drink/eat in while waiting? I recall getting a beer and then attempting to walk one of the trails in Animal Kingdom to be told I could not enter. That is not a line, but rather the attraction itself and there are live animals around.
I just optimized an Animal Kingdom half day where my crowd level has jumped up a couple notches - and it put the safari ride last with a 25 minute wait. It would be nice to grab snacks to eat while waiting.
We will not be using fast passes at Animal this day.
Answers could apply to any line in any park.
