Ask HN: How can I market to SxSW without a badge

I have an mvp that is going to be ready in the next couple of weeks. I'd like to release it a week or so before SxSW to work out a couple of kinks and then go to Austin and market it like hell. I'm not sure how things are set up there(I've never been). Is there a good place to 'intercept' people without being in the convention center?

Alternatively, is there a good way to pick up an 'unused' registration? Maybe someone had an employee registered but is no longer associated with said employee.

SxSW is a unique opportunity for me because I live in Houston and have sister that I can stay with in Austin.

If you haven't figured it out. I'm trying to boot strap this with basically no cash.
