Visit the locations well before the wedding, ideally at the time of day when the various events are scheduled, and make sure you know where the best spots are for photography. Also consider what would happen if the wedding day turned out to be wet or very windy. Check the times with the couple shortly before the wedding, and make sure you understand directions to get from one location to the next, and how long the journeys will take given the route and traffic circumstances. It is very embarrassing to be late or get lost en route.
