You can't go expecting something. Sometimes they will do it, but sometimes they won't. We got free wine glasses at CRT, special placemats and lot of attention at chef mickey's, congrats pictures in our hotel from mickey and minnie and lots of comments from guests in the park. We also got put on the spot by a security guard. he's a big guy that we always see in front of MK. He stopped and shouted our names and our wedding date to everyone in the front.
Good Luck! Wear some pins and maybe hte wedding ears. You'll be surprised at all the magical things that may happen!
