Ooh, I think I might be attending that showing in CT!
However... I HIGHLY recommend AGAINST doing what you have as a plan right now. There are still some tickets available, try to grab one or more of those.
Also, when you say this, how much time did you spend? Even if you spent a few hours, it only takes a few minutes to snag tickets now. It's worth the time.
(Why I recommend against it: I have some experience with bodyguards. They're not mine, of course, but they are very competent when it comes to doing what they do best: protecting. Even though they won't think you're a danger, I doubt they'll let any teenage girl anywhere near him. Doing something like dodging security is something that only works in movies. It won't work in real life, and you'd probably get apprehended before you reach anywhere near the stage...)
