Yes, you can arrive late, and/or leave early.

If you're arriving late: we'll do our best to catch your students up when you arrive, but please go over the schedule with them in advance (either in-class the day before, or during bus ride over). Students will be expected to enter in-progress workshops quietly.

If you're leaving early: please ensure you have communicated a meeting time and place to all your students. Most venues do not have a global PA system for announcements, and making announcements is disruptive to other students staying throughout the event.
