TIP 15: 'Less is more' - sometimes it's more profitable to stay in one session for the duration rather than moving between sessions Chairpersons of short communication sessions are asked to keep strictly to time, so that participants can move between sessions to hear specific presentations on different topics. However, it may be more fruitful to stay in one session and listen to all the presentations, including any discussion at the end of the session. It can also be quite stressful moving between sessions, since some of the rooms may be quite a distance from each other.
