Last minute photography timeline help!!

Hi, my friend is getting married in two weeks and I’m stepping in to help create a timeline for the day. It is proving to be a bit of a challenge, because all her vendors are booked and their individual timelines are set. The photographer is booked for seven hours, the bride and groom are getting ready at two different locations, there is a Catholic mass with an hour between the ceremony and reception, and we have a large bridal party (16 total). How do we make time for all of the important photos? Please help!
