2. ask that your DJ / band / entertainment does this one thing with us, but does not use these:
documenting all of the reception events (introductions, toasts, speeches, dances, etc) in their best light benefits from a heads-up right before they’re about to happen -- we may need to reposition ourselves, our flashes or the person giving the speech and scrambling at the last minute isn’t a good look. ...a simple check-in goes a long way!
You know what else isn’t a good look? A dance floor full of speckled or lasered dancers. Unless you specifically enjoy the look of chicken pox on your guests, please ask your DJ not to use colorful lighting dots / laser beams because they are terribly unflattering in photos!
