Sunset planning tips:

• Tell your guests the wedding starts 15 minutes earlier than you are actually planning for. People often show up late, and timing is critical for a sunset wedding.
• If you want sunset pictures of you together, have your wedding 45 minutes before sunset. That way, you have time to get the pictures taken that you'll cherish.
• In the winter months, sundown can get cold for your guests. Plan for indoor receptions or have heaters around the site.
• Check out a potential venue at sunset, so you can see what your guests will see.
