Bride09,
Hmmm actually I didnt really keep track of the time, as I wasn't involve in the briefing, only the groom and the helpers were there...
But accordingly to my husband they start at ard 6pm. Jason (who is our operation manager tat day) will do the rehersal with the groom, from the dish to the opening of door. What time to let guests in, what time to start, the montage, video highlights..walk down the aisle, music testing, etc.
