My fiancee and i are getting married at the courthouse before we leave for New Zealand.
We'll have a nice outdoor gathering at a relative's property in Sunbury, and we'll have a bunch of guests, and the parents will be buying the food, alcohol, etc.
My mother is a former professional photographer (worked at it for just a few years out of college, but she is still very good), so she'll be doing the photos and the like.
And, as we're moving to New Zealand, that will be our honeymoon.

We're going to have a couple day layover in Fiji on the way, so that should suffice.
She bought a really pretty dress, not a wedding dress, for about $100 at this great vintage store in Delaware. She loves it, and will be wearing that at the gathering in Sunbury.
All in all, we're essentially spending nothing on it. And it is exactly what she wanted, and is thrilled.
That is the way to do it.
