Hi! I too am getting married in December in Punta Cana and am having my legal church ceremony at home two days before I leave. This is a "don't do what I'm doing" post.
My fiances family does everything over the top, so of course now the church is turning into this big to do, with a dinner afterwards that is costing over 5000, 50 (close family only originally turned into extended family and friends who can't make it to the destination) people are coming and because I want to keep my DW special I refused to wear my wedding dress. So someone his aunt convinced me that she would buy me another dress, at the time I got all swept up into getting another gorgeous wedding gown, but now I wish I had put my foot down and kept it to just our immediate family (i.e. parents) and wore a white short dress or suit. Now I have two weddings, way more stress, and it isn't the simpleness that my future husband and I imagined. I am still excited because I am going to keep it christmas themed and make it more of a christmas party dinner but it still isn't what we originally wanted and that definitely puts stress on both my fiance and I. Hope that helps!
P.S. Where and when are you getting married?
