And Finally... Relax and enjoy it!
Okay, now that I've given you all these things to worry about, the final piece of advice I have is to relax and have fun! I know that sounds odd with all the things I've mentioned that could go wrong. I still believe it's very helpful to be aware of potential pitfalls. You'd like the day to occur without a flaw, but you know what? Sometimes things happen. The most important thing is that you've expressed your undying love for the person with whom you want to spend the rest of your life. Don't lose that feeling because something isn't perfect. Hiring seasoned professionals can eliminate a lot of common errors. So I would say, hire the best people; worry about the details beforehand; but on the day smile and go with the flow. It's your day! Enjoy it for the incredibly special occasion it is.
