We had two family weddings this summer - the church was in use by the wedding party far more than one hour for the service…
As most parishoners do not have keys to the building, someone has to be there to unlock and be around for little things that come up.
The church had to be opened at least twice during the “planning” stages while the bride and her mom and the entourage decided on flowers and other such things.
The building had to be open for the wedding rehersal, this was at least 2 hours of time. Then came decorating the Church, that was another 2 + hours of time before the wedding.
The church also had to open classrooms/parish hall for dressing rooms.
Pictures? Those took 2 hours before the guests could come in to be seated - guests began arriving 30 minutes before the wedding.
After the wedding, there were MORE pictures, that was at least another hour.
Then came clean up - our family did the clean up after my neice’s wedding, we had about 10 people pitch in and it took an hour.
Just above, I’ve accounted for 12 hours of time the church and property were at the disposal of the wedding party PLUS 10 man-hours of cleaning time.
AC, personell, insurance, electricity, water, toliet paper, soap, cleaning supplies - a fill blown wedding is more than just an hour for Mass.
