I agree! (Yes, I'm prejudiced; I got married in Las Vegas). It's easy, affordable, the hotels and restaurants are among the best in the world, and it's a fantastically fun place for grown-ups.
Plus, it's convenient: Did you know you can buy a Las Vegas wedding package online? They start as low as $63 (license additional) and you get flowers, cake, officiant, transportation, and memories to last a lifetime.
