I'll warn people about the stipend. It's up to $200 for travel (gas, rental car, flight, train) and hotel stay (hotels are surprisingly expensive around there, I got a meh comfort Inn in the CWE for $100, others went to the Moonrise for a little more. If you sure you want to visit that weekend, start pricelining that crap sooner than later.
However, not everyone gets it. I was technically not supposed to get one. The only reason I knew about it was because of TLS, and I had a question about it, and they gave me some details about it.
I picked up the stipend form at ASW, and turned it in, and then they called me up, saying I wasn't going to get it (it was only for those who were offered a stipend.)
I said I was under the impression that I was to get a stipend, and they asked why, and I sent them the emails they sent me stating how to send in receipts, and then they just went ahead and okayed it.
TL;DR $200 universal, but not everyone gets it. They need to tell you that you get it, but you may be able to ask for one.
