You'll both have little time to be alone with your spouse on your big day. Try to make a moment after the ceremony for some quality time. 
Start calling him/her "husband/wife" for the first time, admire your new wedding bands, and assure some TLC. Arrange with your Wedding Planner to have some hors d'oeuvres and drinks while your guests are at the cocktail hour, so you both can enjoy it as well. 

I am a Wedding Planner in Puerto Rico. I only do Amazing Weddings. Proud to be a top Wedding Coordinator in Puerto Rico.
