We saw it. We were in line the first time, but then right before they were going to seat us, they cancelled the show because of technical difficulties. We were able to see it on our next trip to AK a few days later. They line everyone up and then open the doors. If you got there early, you got a seat close to the front, if you were at the back of the line, you got a seat towards the back. Actually all seats were good.
Similar to Tarzan, there are actors that walk through the theater along the main walkway and then over to the stage. The actors are dressed in costumes, with tight fitting hoods (but you can see their faces) and carry props/puppets like the fish, whatever. Not like Fantasmic where the actors carrying the props are dressed in black so you don't see them. You are supposed to see the actors. Then they proceed to tell the whole story. Show took about 30-45 minutes.
I thought is was okay, but more of a been there, done that show.
