Videography or photography of the reception is a popular idea, but it is important to clearly discuss with these professionals how intrusive or out of the way you want them to stay during the reception. If the videographer or photographer is to get the best shots, they will need to be in the right position, which is usually in the center area of the room.
Know what the plan is for the evening. Have a written agenda that includes events such as the time of the speeches, the time of the meal, first dance and when the DJ or band will start. All the professionals and performers should have copies of the agenda to help everyone stay approximately on schedule.
