Before we left for our vacation, I wrote a letter (that I brought with me) telling the CM that it was my DH's 50th birthday during our stay. I asked them if they could do any "Disney Magic" for him. I also told them that we had reservations for the Hoop de Doo review on his birthday. I discretely gave the letter to a CM upon arrival. Our room was not ready, so we went to the park. When we returned, they delivered a autographed picture of Chip and Dale attached to a happy birthday balloon. They also sang happy birthday to him at the Hoop de Doo.
I also ordered a T-shirt before we left that said, "I may be 50 today, but I'm still younger than Mickey!" Everyone stopped him to remark and laugh. The back of it said, "My wife and kids made me wear this shirt". He was mortified. . . It was great fun!
