With the kids, expect huge delays. Ask your photographer, but also remember that backgrounds are not important, actually, lighting is.
Remember that very, very few bridal party photos make it to an album. I have ten in my personal album that feature ‘maids or ‘men, that’s it.
Are they all taking their own vehicles or do you have a limo? Will the bridal party be drinking alcohol?
Account for weather. Will it be really cold in Minnesota at that time? Account for people’s temperments. Remember that most children, pregnant women, and even the men will not generally enjoy doing a shoot for hours as models.
If the ceremony is at 4:30, you just work backwards.
