Honeymoon and Other Travel: Light Packing?

I found this website and I was totally curious whether anyone does anything like this:

One Bag

I will admit to be nerdy enough to absolutely using a typed list to check myself against any time I travel, but it is much much longer and includes lots of things I don't need!  I just thought it might come in handy with Honeymoon planning and other travel (since so much is associated with weddings).  Let me know what you think!  And remind me to use this when I actually pack for my honeymoon.
