Just wanted to add a short note: registration is in the "A" section of the Convention Center. I noticed this isn't very obvious when you're coming in from the DART-rail. If you're using DART, when you exit follow the signs to the convention center, and then follow the signs to "A." (But don't worry--if you end up in the wrong section of the center, there are lots of helpful TLA people at information kiosks to get you on the right path!)
