Sometimes there are more than one seatings for that event. You could stop by the counter near the entrance and find out what time seating starts on your day. I know that when I went there was only 1 seating around 4pm. I noticed the last time I was there the time was 4:45pm. In the summer they've had two seatings at around 1pm and 5pm, so I would check on the way in. Maybe their web site would have it listed http://www.seaworldorlando.com Or you could call them at 1-800-327-2424
