This is something like what I'm planning, church then followed by lunch. But I'm skipping the first part. No pick up or tea ceremony in the morn, will prob do the tea ceremony later after everything.
Me and my fiance initially wanted to do it on sunday, but figured that it will be too rush to have our church in the afternoons, so we're changing to sat to save me some headaches. we'd prob do a wake up, get ready for 10.30am church ceremony then head to restaurant/hotel for lunch around noon. I think there's enough time, and mine is a church service and not full mass.
of course it helps if ur church is not too far from ur hotel/rtn!
