When Uni first started with security it was a nightmare, they have really learned and improved. I have had it that I arrived early and it seemed like it was going to be a nightmare because the whole pre-security area was full of people, yet generally it always ended up going smooth. Probably it could use some streamlining though. Seaworld on the other hand, that can be a nightmare, though a lot of it is because their entire turnstile area is way too small.
