We went on Christmas Day evening in 09, so I don't know timing for Christmas Eve. The show was really festive. We went early, of course, to get good seats, and they had wonderful musical entertainment before the show. The show itself was about the same length as Believe and Shamu Rocks. I thought Sea World was a perfect place to celebrate the holiday. Going out of the park, the evening sound/lights show even had real snow falling down and great Christmas music.
