Identify the people and companies you'll need to make sure your event goes off smoothly. Anyone from the event coordinator to the valet parking team should be a part of this list. Be sure they know exactly what their role is, what's expected of them, what time they need to arrive and any other information you feel is necessary. Set up meetings throughout your planning to keep everyone informed and updated. Be sure to have a pre-event meeting to go over any last minute logistics and troubleshoot as needed.
