Im writing this with a bit of trepidation, because my original intent was not to be critical, but to point out what I have seen and perceived as a truism with kids, elevators, and curiosity.
I know that everyone is clamoring about overweight children, but my children have always been taught from day 1 to have curiosity, and to wonder about things, how they work, and to experience different things (safe things). I have used the elevator on the ship as a game, as a way to teach numbers, and just as a way to be in awe of the beautiful ship that is the Disney Magic especially the midship elevators that rise above the atrium. We also make the stairs a game too, and can have fun going up and down those.
Im sorry if I offended any politically correct idea of what is acceptable. Elevators are not a bad thing in and of themselves, and I must admit, if I am really tired, I may take the elevator instead of the stairs. Im sure that it would also burn more calories to swim instead of taking the ship, but I am sure no one would advocate that.
One of the fondest cruise memories I have is of waiting for the elevator with my then four year old midship, and the doors opening to reveal Mickey and Minnie going up with a CM for a show on deck 9. My daughters eyes were like saucers as the CM told us to come on in for a ride, and my DD hugged Mickey and Minnie on the way up and I didnt have my camera!
