I understand completely what you are going through. We got engaged July 30 of this year. We had told my parents that we were looking into doing a destination wedding. My mother is not a flyer. She has some medical issues and does not like to fly. It really tore me. I actually changed my mind to have it here. On August 30 my mother passed away. Before August 30, I could never imagine havig a wedding with out my mother. Now, no matter where I have it, she wont be there. It is the worst possible end result. My dad had told me that my mother would have come around. That she would never had missed my wedding. Give your father a chance. There is still time and it might just have to be an idea that gets through his head.
