The demonstrations are open to all attendees. You don’t have to register for specific rotations – just show up in the room at the right time.
We try to schedule most demonstrators for more than one session, so you can usually arrange your schedule to avoid conflicts with other things you want to see.
We usually post a rotation schedule of demonstrations in August. In the mean time, you can get an idea of how we schedule things by looking at the 2019 schedule.
