Wedding stress

I can't believe the wedding is only like a week away! There's still so much to do. I have a meeting with my photographer next week, and a million things to do this weekend. Mostly I'm stressed about the money. With 320+ guests it's EXPENSIVE. We're meeting with a woman from the casino tonight and have to pay 25%. We'll probably pay the whole thing since it's due 48 hours before the wedding and we don't really want to head back up there. We're going to be broke after this! My grandma asked me this week if I needed any money...may have to take her up on it. :)
