-If you haven't had a wedding planner throughout your planning process, now is a great time to splurge (if you can fit it into your budget) and spend anywhere from $800 to $2,500 on a good "Day Of" coordinator, depending on your needs.
-If a Day Of Coordinator is not in the budge, spend $300-$600 having someone coordinate just your ceremony, if you don't have someone at your ceremony venue that comes with the package.
-If you have a church (or elsewhere) coordinator and don't have the budget for a Day Of Coordinator, make sure you make a complete wedding day timeline for the head of food and beverage and go over it with him or her in detail. They will be your de facto coordinator on your wedding day.
-Get some good nights' sleep! For goodness sake, put down the seating charts and REST. You don't want bags under your eyes or to be snapping at everyone over every little thing because you are tired. Crabiness from exhaustion does not go away just because you're not a baby.
-In the same vein, drink plenty of water. You'll flush out your system and feel healthy, it will give you more energy, and it will make your skin glow.
-Try and get every errand run and go over every last detail so that you can let go of your wedding on the Wednesday before (or three days before, depending) and trust the experts. You may think I am crazy for suggesting this but if you've planned well, this is possible. And you will be so thankful you did!
