- You will need to call the Temple for an appointment. The earlier you call the better chance you have of getting the day and hour you would like.
- You can request a particular size room so all your guests will have a seat. The rooms are not large, so you should carefully limit your guest list to family and very close friends.
- You can request a particular sealer if you wish to. That request should be made to the temple when you call, and also to the particular sealer you have chosen plenty early for him to schedule and to get permission if he needs to. General Authorities can seal in any temple. Regular sealers, or sealers who are retired from regular sealing, are assigned to only one temple. They can seal direct descendents in any temple but must receive permission from the First Presidency to do so - and that takes a little time to get letters back and forth.
- You will, of course, spend a good deal of time with what to wear. Please be sure you dress as recommended and that you school your desires and feelings, your attitude, to be in tune with that - so you feel good about it. If you come to the temple feeling excited for this wonderful opportunity, and willing and anxious in every way to to be ready for this experience, you will feel the Spirit there and leave with wonderful feelings inside, and ready to face the world together.
This is just a thought or two I've had as I've observed things at the Temple.
