Wow. This would be completely out of my league, and really, in my mind, a bit excessive. I have a friend that did this kind of wedding for her daughter and within a couple of years they divorced. What a waste of money. Your daughter and future son in law are sweet and tolerant to go along with it. I bet they would have been happier with what you were more comfortable with. But it is to their credit that they are indulging the mother. Is this not supposed to be about love, and a promise to be there for each other for the rest of their lives? The bigger is the extravaganza the more room for glitches, I think. But I think your daughter is giving, she will rise to the occasion no matter what.
I could afford, say 50-75 people, with wine. And I would cook.
Gee. I wish my son would get married. But first, I would like him to move into an apartment, off the street. And a job would be nice.
