As much as we adore your children, no. The only children that will be in attendance are immediate family and/or those in the wedding party.
There are many options as far as airports go so really it depends on how much time you have and how much you want to pay. Flying into SLO is the most costly but convenient. Flying into LAX is probably the most cost efficient. Flying into the Bay area (San Fran) and driving down the Pacific Coast Highway is probably the most scenic.
