Nadin,
While I don’t have much use for your condescending, all-knowing, it’s-all-about-me attitude, I do have a serious and sincere suggestion for you.
You have access to what is arguably the most famous/popular comic convention in the world. Due to the fact that it is so popular and due to the recent comic based blockbuster movies there will be a ton of media at the event. Almost all of that media will be covering the product (comics, movies, etc) or cosplay (and similar) events. You have the opportunity to do something different.
In my opinion, one of the most interesting aspects of any comic convention are the fans in attendance, and I’m not talking about the fans who walk in wearing their regular street clothes. I’m talking about the fans who show up in character (and not the ones there for cosplay events or to serve in booths). These are fans who (1) have a true love for the genre (2) are still young at heart and (3) have a bit of an adventurous spirit. Granted, some are just crazy, but many just want to feel involved and demonstrate their creativity.
I suggest that you focus on these fans. And not just to take their photos like most people do. Talk to them. Find out why they do what they do. How long it takes them to prepare. What concerns they have putting themselves out there in their costumes.
If you do that, you will be doing something unique, and on this very website I will commend you for it.
