We arrived just before 8 yesterday. Let into park at 8 - we weren’t that close to the front and got to area around Tiffins around 815. Opened FOP and navi at 830. Nice surprise!! Other parts of the park didn’t open till 9.
this does not surprise me, my daughter is currently down there on the Disney college program,working Pandora, if she opens she must be at the ride by 530AM so I'm guessing with the crowds once they are sure the ride is up and going having that extra 30 mins helps alleviate some of the crowd. But yeah it takes 3hrs to bring that ride up.
