First, are you having a casual, formal, black tie, or white tie wedding?
Who all did (are) you invite to the rehearsal dinner? Are you inviting spouses and step family?
Who all was (is) in the ceremony processional (or rather who all is walking down the aisle before the bride, but after the guests)?
How do you feel about the groom walking down twice (once with the eldest family member, second with the his mom)? I can't stand the idea of anyone walking down twice or walking alone (just my personal preference, I don't judge anyone who does this). I see it as tacky for the groom especially to walk down twice (I mean, I only get to walk down once. Haha.).
Just trying to see what everyone is doing because my FH and I are in a disagreement about these things even though we originally agreed on them.
