I will second what AH-1G said, I shoot weddings frequently and the guests have never said anything. The most common problem I run into is the guests start hovering around me asking questions while I am trying to fly. But yeah during the actual ceremony, when they are saying their vows I always have the bird grounded.You would be the best one to ask, did you feel the noise from the drone was obtrusive to the guests? Also, were you using an ND filter. I'm a bit disappointed with the type of flares that I get with my Polar Pro ND's. Nice footage by the way.
