You probably want to have a hotel lined up already.  Just make sure it's not "Advanced Purchase" for now.  So, if you don't go, you can easily cancel.

At this point, anyone without a hotel reservation should strongly consider renting a car as well.  You won't want to pay hundreds of dollars each night in downtown hotel, so you will need transportation to the convention center.  Downtown parking across from the convention center is $12 a day (as I understand their parking information).

For me, I'm driving in, as I'm paying my own way, so I went with a cheap hotel room that's about 10 miles away from the downtown area.  After all, I'm mainly going to sleep and shower there each day, and if I'm back at the hotel before 10 PM each night, I'd be surprised.
