Dude, do you have a place to stay in Austin? You are absolutely welcome at my co-op! I will be gone June 22nd-30th but any other time is fair game although I work during the day Mon-Fri so you'd have to work around that. Be forewarned that as a co-op it is quite... communal. I have room for probably one of you in my room on a mattress and for the other on a couch out in the open in the common area of one of the suites. Alternatively, you can "hostel" for $14 each a day, which means you could both get a bed in a room, assuming there is an extra room for hosteling.
