the biggest wedding I ever went to had 500 (I think it was the biggest, I'm not good at guessing these things but this one I know cuz the bride told me) and it was in a freaking airplane hangar, or it felt that way.
edit: I mean the reception was in an airplane hangar, the ceremony was in a church
We have huge marriage halls designed for the very purpose
of course I am old, that's why I don't want anyone to know
Didn't you get a "aha moment" like that stupid ad that gets aired on TV these days
