We are getting married July 2013. Once we have confirmed our venue, we will send STD so that our OOT guests can take advantage of the blocks for accommodations/travel (We are both members of AAA and hoping to get discounts on accommodations/travel for our guests through our membership) However, I was told that I need to send an announcement. Personally, we think it is a waste of money that could go elsewhere. Can someone explain the difference between STD and Wedding Announcement?
