It certainly didnt hurt my Disney experience. I may have been the ones that now has an "enhanced view" of it.
I have seena charecter with his head off in the tunnels before and it didnt phase me at all, since I knew they werent real anyways.
The magic of Disney to me was the guests. There were days I absolutely hated my job, but then we would all head to the parks and my perception changed quick.
Stand there at Wishes, Fantasmic, Illuminations, the Stunt Show, or anything pretty much and watch little kids eyes light up with fascination and joy and you get a deeper sense of appreciation for what you are doing.
Everyone here plays a role in the guests experience, no matter how insignificant you may feel it is...but it all adds up.
When we had rough days at work, a trip to the park is all it would take to cheer me up. Watching all the little children having the time of their life made it "magical" to me.
So what If i know what Rock n Roller looks like with lights on, so what if Im "friends" with half the Disney charecters....they all provide a dream that becomes reality to millions of people.
That is what Disney Magic is to me.
