Okay I have a tip if I can remember correctly. When the park opens don't go the normal way to the penguins. Go the back way. We were told to do this by a worker and we were first in line. They hold everyone up at the other end, I believe, not sure since we did not go that way. But we walked around going towards the sky tower and then over and there was no one but us. We walked right up as they were opening. I even had to ask, are we in the right place? Thanks to that worker we had no wait, no lines!
