Secret weapons: Master & Mistress/Matron of Ceremony

Your best wedding tool is your "army". And the most overlooked jobs are Master & Mistress/Matron of Ceremony. You can choose 1 person or a married couple you admire. They should be people you feel will get the assigned tasks done without much direction from you.
They can do things such as:

• run interference between quarrelling guests (or even between you and certain family members!)
• moving items (flowers, decorations, etc.) to another place after the ceremony
• help clean up after the reception
• drive you & the groom in a special car from the church to reception (who needs a limo? rent a cool luxury car!)
• organize the events at your reception (cake cut, bouquet toss, 1st dance)
• help round up folks for formal photos so they move along faster - I highly recommend this!
• organize the wedding party so they walk down the aisle correctly
• be your advocate about how you want things done in general

Remember the "Mistress" would be an unmarried woman, while a "Matron" is married. And a small thank you gift is definitely required for all the work they'll do!
