I just had one aboard the Magic last month. I was going to save it for the trip report for that day but I'll share here as well.
It was our last day at Castaway Cay. After we got back onboard the Magic we changed for dinner and then went up to Deck 10 to take photos and video. We have a digital camera but still have a Sony Hi 8 video camera that takes tape. While I was video taping the camera stalled and I thought maybe the battery was low. Not the case....I go to eject the tape and it had become unravelled. I tried fixing it topside but it was too windy and my finger was too big to roll it back up. I told my DW I was going to go back down to the stateroom to try and fix it.
I get on the forward elevators on Deck 10 to go back down to the stateroom and press Deck 5. The elevator stops on Deck 8. The door opens and there are a couple of kids there but no one seems to be getting on the elevator. So I figure someone is playing with the buttons when someone from the right puts their hand on the door to hold it open right before the door closes. It was one of the ships officers and he apologizes for the wait. I tell him no problem and figure they might be getting someone in a wheelchair or physically challenged.
All of a sudden Mickey Mouse walks around the corner and enters the elevator and the officer follows. Here I am with Mickey Mouse all to myself in an elevator and I have a busted camera. I am so stunned that I say "Hi Mick!" I have never called him "Mick" before so I asked him if it was okay that I call him Mick. The officer says to me that it looks like I'm having camera trouble and "Mick" points to the tape, places his hands to his face and shakes his head. I say "I think someone is telling me to go digital." The officer laughs and "Mick" laughs and puts his hand on my shoulder to console me. The elevator stops at Deck 5, the officer bids me farewell and "Mick" waves goodbye. I say thank you and to have a great night.
What a wonderful experience that was. I thought it was great that "Mick" never broke "character" even though I was an adult with no kids around. Maybe they just know that even though you are an adult, being on a Disney cruise means you're still a kid at heart.
