My best tips for your temple sealing:

Not only does this help set the tone of the day and give you time together beforehand, it’s also often the best time of day for lighting and will reduce some of the chaos and pressure of the afternoon and rest of your wedding day! I especially recommend this if your sealing is in the middle of the day.

Some temples have you come out the front door, others have one or multiple side doors. You’ll want to know beforehand so that you can let your guests (and your wedding photographer!) know in advance where they need to be
You are usually not allowed to bring flowers into the temple — assign someone to meet you at the door with your bouquet and boutonniere right before you exit

Plan something fun with your partner for right after you exit: a spin, kiss, dip, high five, big cheer, or anything else that reflects you guys. It will make for a fun photo, but more importantly it is fun to enjoy being the center of attention just for a little bit!

After you exit, you can take a few minutes to give hugs and say hi to your friends and family before jumping right into everything else! You just got married! It’s exciting! Take a second to enjoy it. You don’t need to rush right into family photos or wait to be told what to do.
After your sealing and any photos are done, take some time to yourselves. Write down what you remember from your sealing (you’ll have a hard time remembering later) or make a video or audio recording together to watch later. Stop and grab a treat or a drink together.
