A destination wedding can be as cool and casual as you like. Want to wear flip-flops or barefoot and dig your toes into the sand at a beach wedding? You got it! No heavy brocade wedding gowns or stultifying tuxedoes required, either. Make the ceremony as short as you like, then strip down to your bathing suits and swim away. Or head to a patio, start the music and champagne toasts for a party that can last until the stars com out.
