It can be, but just like WDW, the pros outweigh the cons. I love what I have done for over twenty years and would continue for another twenty, except I know I am meant to be Sorcerer Mickey's "friend" at the end of Fantasmic one day!
I have seen changes in kids, parents and, I guess, society, over the years at work and at WDW. My "kids" have more issues these days and WDW has more garbage tossed around (don't worry, my husband picks it up all day long saying, " not in my house"). I just stay optimistic, hopeful and patient that each day will be fun, positive and productive for everyone, which is why I always wish everyone "a magical day" everyday!
