Eat as per normal, dont drink and dont have the cake say your no thank you. Dancing is a good idea, drink lots of water eat the meat and salad/veg, avoid the bread and potato if you can and you'll be fine.
Expect a gain of a couple of lbs the next morning but after a day of CD and the following morning I reckon you should be back to normal. Try not to weigh yourself until you see your CD that way you wont know about the gain and make yourself disapointed or feeling low, you dont want to continue a deviation from the diet except for the wedding.
Also enjoy yourself! It is a wedding and try not to feel guilty eating.
