I spoke with Shaniece Morris at the resort. I chose my locations for the ceremony and private reception and then she emailed me a form to print out and complete. One of the pages was a credit card authorization for the deposit of $350 (i think that was the amount). Never was I asked to wire funds. Unless something has changed?? I would speak with her about paying by Visa so that the payment is secure, and make sure to ask her to send you the paperwork.
Let me know how it goes!
