If you don't already have them, get the Mickey & Minnie bride & groom hats. My fiancé got them for us after he proposed at WDW and we literally got special treatment (and free stuff) everywhere we went. You can even get them embroidered with the date you got married on the back. Find a Photopass photographer to take pictures of you two in your hats at all the major spots. Most of them will go above and beyond to get you some great shots. We even had one that took our picture during Wishes, and another that took us around the World Showcase at Epcot and we got our picture in every country. In addition to the "Just Married" pins (which, by the way, they don't always have. Sometimes they only have ones that say "Happily Ever After"), there's a set of "Mr. & Mrs." pins you can buy at any pin shop. Not sure if this is the kind of stuff that you were looking for, but it's things that my fiancé and I did right after we got engaged and it made the whole thing even more special and memorable!
