As a wedding officiant who specializes in custom ceremonies I often ask the people I am working with about the logistics leading up to the wedding day.  Many couples are planning their weddings themselves and while they may have an on-site  coordinator, are often not unaware of how overwhelming last minute preparations can be.  Coordination of musicians and the officiant, coordination of amplification for the ceremony, flower location for the ceremony and then the reception, timing of the photographer and bus shuttles, gift basket delivery, marriage license and the list goes on.  While many site coordinators do a terrific job, the extent to which they are looking at all the details leading up to the day is limited.  Bernadette Smith of It's About Time Events talks about all the details that a day of wedding coordinator will handle for you in her Blog.   I have officiated at several weddings where the stress and tension of these details caused many a tear.  The day of your wedding should be joyous and as stress free as possible. If you are planning a wedding at a function hall, hotel, etc. I highly recommend considering a "day" of wedding coordinator to alleviate stress and worry and allow you to focus on enjoying your day!
