Tyler Cowen is offering wedding advice:
Non-contractibility is a bigger problem than you think. You can agree on the number of people, and the amount you will spend on flowers, but ex post many questions will pop up at the margin. One of the two persons will care more about the right answer than the other. One party will be more willing to work on the wedding than the other. Contract in advance for a method of disagreement resolution, not just on the details of the wedding. Get ready for the fact that one person cares less about the wedding than the other and realize this is not the same as caring less about the marriage.
More here. Ah, yes, I remember. The problem we had is that we were both in a game of chicken, as two grooms really didn't care that much about the wedding as such. When the game ground to a standoff about a month before the wedding, we desperately asked our friend, Bryan Rafanelli, to rescue us. He did. We really are bad gays sometimes.
