Mrs. Wookie's needs for a great time at a wedding:
a.) I will only go with Mr. Wookie. I attended a wedding sans Mr. Wookie (he was in flight school and couldn't get away), for some friends from college, and it was torturous being alone. I will never do it again.
b.) Please serve alcohol. You want people to dance? They need some sauce in their system. However, just be sure to have toasts (if you have any) before the sauce gets thick in their system.
c.) Please serve delicious food. I don't care if you choose heavy appetizers because they're cheaper, or a full-service meal. Make it tasty! You're essentially hosting a dinner party if you're choosing to have a food-based reception. Don't suck at it and leave me with crackers.
That's pretty much it. Not too high of demands. I mean, I could go into detail about how I love wedding websites, coordinators, and non-strapless dresses...but they're not as important.
