I do think they could've easily re-themed it as part of HP - Chamber of Secrets something or other.
It's fun to do once. We won't do it again get though. I do remember being in a tunnel waiting to get into the show. Although it was nice and cool inside, it was hot as hades In the tunnel. And of course,certain individuals were present from areas that obviously have never had deodorant delivered to them. That's one smell I can't handle!
I liked it but it felt like forever to get through the line and into the show. I almost gave up. I thought the effects were really good.
