Press exclusivity?
The poster of this one notes that you can get into events, conventions, and concerts free of charge by requesting a press pass. I do not see how it would work, as you typically need to present credentials on the spot or send a link to your writing profile.
If nothing else, it could be worth a try, but I think your chances are slim-to-none. Perhaps if you want to push your luck, you could say that you are a blogger and it might work, but a member of the press requires special credentials to get into such events and to surpass paying.
