Two things you'll want to think about.
- If you don't want to have what I like to call an accidental processional that will take 30-60 minutes, make sure you and your groom go some place where your guests won't run into you after the ceremony. If you are in an open area and have a hard time finding a place “away” your officiant can announce to the guests that you will greet them at the reception.
- If you do plan to do a processional make sure to leave lots of time for greeting all your guests.
Either way I highly encourage a moment alone just you two to let it all sink in that you are now married!! Rejoice lovers! ;)
