What is everyone doing for the order everyone walks in for the processional? This is a "non-religious" ceremony, so not following any strict traditions. I'm trying to fit in these folks:
Officiant
Groom
Bride
Father of the Bride
Mother of the Bride
Mother of the Groom
Father of the Groom
(Possibly grandmother of the groom if she feels up to it)
Best man
3 additional groomsmen
Maid of honor
5 additional bridesmaids
