Be sure to get the "just married" buttons from your resort or at any Guest Relations desk. People will congratulate you you everywhere you go, and you may get some special treats from castmembers!!
Also, be sure to stop by Snow White's wishing Well. Both of you throw coins into the fountain - and when you are asked what you wished for, say you didn't wish for anything because all your dreams came true when you got married. Schmaltzy, I know, but chicks dig that!!
