I wanted to make at comment about sessions for bloggers. In Ballroom B there are tables set up in the back near outlets. I discovered this would make a perfect area for a blogger who needs an outlet to keep the computer power during the sessions. My experience blogging has been tricky because I have to scope every room I enter for an outlet, and then have cords in the way of other attendees that walk between the walls and the chairs.
My first session I ended up sitting on the floor near an outlet to finish writing.
I wanted to point this out so that planning committees can prepare for this when setting up rooms.
