This was the one thing we used a FP for that we thought was pretty useless. We entered through the FP entrance but then you all wait together in the holding area. We had never been there before so we went down to the front on the right side. Well, the doors are all on the left and the CM's made an announcement that the front door only leads to the first couple of rows with very few seats so most of us should use the doors further back. We ended up waiting for almost everyone to enter and went back up the ramp to the top door to enter. It was not a big deal in terms of seating because we had no need at all to be in the front, we just wanted to see the show it didn't matter where. It just wasn't a very efficient use of a FP for us.
ETA: We loved the show and am not complaining, just sharing that for us a FP was not necessary since we got there in plenty of time and once you pass by the tap entrances you all blend together anyway.
