FH and I are doing a first look at venue (ceremony site and reception are at the same place, but our getting ready location is at a hotel 5 minutes away). Our first look is going to be at 4:00 (the photographer said it'll take about 1 hour) and the ceremony starts at 5:30. We're doing wedding party photos and family photos after the ceremony. But we're unsure of when to tell our wedding party they need to be at the location by. Is 30 minutes before the ceremony too soon?
