The best wedding reception I was ever at was done by the family. It was outside and Cajun. Some of the worst were done by uber professional wedding planners. If you get the food and drink and order of things correct everything takes care of itself. (After you lose your mind the last month before the wedding. My wife was certifiable) Ignore the little distractions and don't let anything short of the groom not showing up bother you. Even if you brother in law tries to destroy the wedding cake before it is cut.
Okay I will try to remember all that *lol*
