I enjoyed my visit even though it was extremely crowded. I got my tickets online thanks goodness because the line for tickets was massive.
The shark tunnel was packed however we didn't wait in line for the moving sidewalk. Instead we walked to the right and were free to explore at our leisure.
Im guessing once school goes back it will be much less busy and more enjoyable.
The $30 price tag is steep for what you get. But I understand how expensive it must be to run the place.
Thank goodness I don't have small kids, I would have been a wreck trying to keep track of them with the hoards of kids that were there.
Over all I really enjoyed the whole experience.
