Save The Dates have become very popular for brides and grooms to communicate and create excitement for their upcoming wedding. It gives the couple a way to let their guests know their wedding date and accommodation and travel information for their wedding. They also can get guests excited about the upcoming wedding! I find they are useful for not only destination weddings but weddings in the bride or groom's hometown. Living in a big convention city like Chicago, it is important to let guests know about the hotel rates the couple has set up for their guests and proper information for booking.
