Best advice I can give is make the day about her. Spend time with your bride. It's tough because there are so many people to see and talk to, but go around together. I felt like I rarely saw my new wife until after the reception, and now I see her all the time. Now I wish I had put in the time up front and maybe had some free time now. Kidding about that last part, but do make it about her, not about friends and a party.
Also, mean every word of your vows, since they are just that. Take it seriously and you won't trade it for anything.
My brother is getting married today as well and I'll tell him the same thing. Good luck and congrats!
