When choosing to include parents and other special guests in your processional, it is often much better, photographically to have those guests who are there as a couple be escorted by their significant other rather than an usher. Often when the female VIP is escorted by an usher, her significant other ends up walking behind them on the way down the aisle. If you instead allow a couple to enter together during the processional, they are photographed together rather than potentially with a stranger (usher) and no one is left in the background of the image.If the VIP does not have a significant other, or they are otherwise occupied, having them escorted by one of your ushers or groomsmen is a lovely way to make them feel special.
