Hi Reuven,
You'll want to make sure you get your open space on the open spaces board during the conference. I recommend showing up early on the 2nd day to ensure there's a mid-day spot available that works well for you and to increase the odds of others seeing the open space.
Personal note: Since I'd like to attend this one as well, I'd love it to not be during my talk at 4:30pm on Saturday. Raymond Hettinger's talk is at 3:15pm on Saturday so might be best at a time other than that also. Maybe 2pm on Saturday would be a good time to try for? I can help promote it to other trainers I know who will be there as well.
