Without thinking of it, I had had both weddings take place at the bridegroom's residence in the first draft.
In the second draft, I thought I might have one take place at the bride's -- and finesse the second one as a special case. It is, in my reading experience, a much more common pattern for the ceremony. (Though of course it can involve moving the bride to her new home in the course of the ceremony -- the ceremony itself begins in her home or its vicinity.)
Then I look at the manuscript surgery necessary and quail. And reflect. And consider that this would take a good amount of space that at first glance would not move the story forward. It might sprout something, it could world-build and develop character -- but on reflection, I think a bridal procession will bring the bride to the bridegroom's, where the ceremony will be held.
Sometimes the first thing you plopped down was right.
But now I have to consider whether bridal crowns are appropriate.
