We renewed our vows thru Jane at gifts of a lifetime. It was on the beach at the poly, Jane arranged to have flowers for myself and our 3 girls. She got all our kids (6 of them) ear hats, the girls had some pink vieling on them, which got many comments in the parks. I had the bridal ears, and she got my hubby a MM bow tie.
She took pics of our "ceremony". We recited the vows we used at our wedding, and our kids did some bible readings. It was basiclly a "do it yourself" renewal. If you want any kind of religious person there to officate you need to go thru Disney. At that cost we decided to go our own route.
After the "cermony" we had an O.J. toast. Jane can do just about anything you want. And she's GREAT to work with!
