I can't believe there are no morning or afternoon breaks, only a lunch break. Seems to me that a major reason for conferences is networking, and at every other professional conference I have attended, networking at tea breaks is a very valuable and important part of the programme.
Obviously people can just skip a session and go outside the lecture theatre and hang around in the halls and talk if they want to, or wander off to a nearby place to get tea, but those seem like poor alternatives to me.
I guess I come from a totally different world.
Thanks,
Jean
