Vow renewal question- HELP!

My fiance and I had planned to get married the day before we left for CN and do a vow renewal on our honeymoon. This is our second marriages and we wanted to avoid all the legal stuff with divorce, etc having wedding in Jamaica. After booking the Vow Renewal ceremony I'm seeing in the fine print that we have to send a photo copy of our marriage license to the resort 45 days prior to the renewal. Does that mean we have to get married before then rather than right before like we planned. Any help appreciated greatly!
