For some reason I think that each resort handles it differently, it was one of the reasons that FI and I decided to do a symbolic wedding versus an actual ceremony. Remember, if you have a traditional ceremony it will be in spanish, and if your guests don't speak spanish you will have to employ the use of a translator. another added cost. I think you might be at the mercy of the resort with regard to the costs. I can't see how you can lower the cost because these requirements are to be completed through the resort in order for it to be considered legal. Have you spoken with your WC about how to cut corners on cost?
