Most meeting planner checklists and conference planning guides, such as the one described here, put too much pressure on the meeting planners. Most of the tasks have to be documented by the planners themselves on such meeting planner checklists. Moreover, you cannot afford to lose your meeting planner checklist probably because you have not only documented all critical activities there but also because you have pinned vendors and contractors receipts and bills to it. The latter you certainly cannot afford to lose. On the day before the meeting, you have to make sure of everything that you have planned for months.
