My fiancé and I are attempting to plan a wedding during his summer block leave next year. We can kind of judge the timing based on the dates this year and the year before, but obviously booking anything without a solid calendar is going to be difficult. That being said, is it proper etiquette to inform our guests that we are considering 3 different weekends or should we wait until we have a better idea of the timing? It's not likely that we'll have any idea until early next year and friends are already being invited to other weddings. I know... the downfalls of being a military bride, but we want to do this the traditional way and are doing our best to make sure everyone is included.
