OK, no one ever answered my question but for anyone else who is wondering I can tell you we were there today, Sunday, 10-1-06 and it was somewhat busy but not too bad. All of the shows didn't completely fill up and you were able to ge there within 15 min of show starting and still get in. We were able to feed and pet the Dolphins in the morning and afternoon, moderately crowded there.
When we visited in July during the week it was a must to get to any show a good 1/2 hr before show start time so it wasn't bad today. I will bet next weekend it may get more crowded with the Halloween Spooktacular starting.
