Yeah, my wife is Catholic; we had two options for wedding. The 1 hour ceremony, or the 40 minute ceremony (I think the difference is serving communion). That was it. I don't think we could have gotten a 3 hour ceremony even if we'd wanted it; they need the church for other things.

As someone who hasn't gone to mass in forty years, how long is it usually? I imagine a hundred and fifty people taking communion would take a long time just by itself.
