We were there in October and I searched (for 9 days) and asked everyone for them... No luck. I continue to check the Shop Disney app but so far I haven't seen them. We were hoping for a cute photo opp signing the marriage contract :/
I actually ran into DFTW at a wedding expo here in Orlando and they were giving them away. I have them sitting in our pen cup on the kitchen counter. So, they do still exist! (Or they did two weeks ago, anyway)
According to my coordinator they have been replaced by the box of stuff (collar stiffener, shoe bag, charm for bouquet, coin for the groom, Mr and Mrs handkerchiefs etc)
