Always keep a crew shirt handy, never know when you are going to need to sneak into an event!

I wonder if posing as health inspector or liquor board might work.

Fire inspector because they are responsible for doing spot checks on crowd sizes. I've been in a club before that was shut down because the fire inspector came in and counted it to be over capacity. The only problem with this plan, beside any kind of penalties for impersonating an emergency official, is the bouncer might get suspicious when he sees you on the dance floor with a drink in your hand.

In the USA, not the rest of the world. Making that distinction because the high visibility vest trick will also work in most other (western?) countries.

@latexr It will also work in non-western countries too... as long as you're the obvious skin color or race. I doubt a white man in Nigeria with a high-viz vest is not gonna attract everyone's attention :)))))))
