When we made ADRs last year at Guest Relations in Epcot, the CM asked if we were celebrating anything, and we told him and he gave us the minnie & mickey wedding buttons. We didnt' have anything special at Le Cellier though (where we ate). On the trip where we got engaged, we had our "last" lunch at CRT, and my DH told them we had just gotten engaged and when we got to our table, there was mickey confetti on the table AND our server gave us a pair of CRT champagne flutes as a congrats gift!!! And we actually used them for our wedding toast! There was no special treatment at DLP on our honeymoon, but we were pretty quiet about it- no wedding ears for us! We also didn't mention it at our anniversary trip to DL this past April. We were also at DL for my birthday last year, and my DH did mention it when we ate at the Blue Bayou and I got special dessert.
Anyway, tell 'em!
