Are you referring to the "re-hitching" ceremony they do at garden Grille at THe Land in Epcot?
If so... dh and I had this "sprung" upon us by well-intentioned SIL and BIL on our trip last year. It consisted of a ceremony, of sorts, with the staff playing the role of minister, characters there as witnesses I suppose. DH and I had to sort of re-take our vows, and then "lock lips for 100 seconds". (They then let you get by with 10, or at least, that's what they did for us, b/c dh was positively fuschia with embarrasment ). It wasn't what I'd call a serious event, by any means -- a very lighthearted, fun sort of event. (afterall, Mickey's in that less-than-attractive farmer suit that "makes his stomach look all weird", as our kids pointed out more than once... how serious could it be?)
