Personally ..... I think this is a bad idea. With finer dressing comes finer, dressier shoes. It is the SHOES that concern me. Women will be wearing higher heels, and possibly getting on rides with high heels. This is not a safe thing in a theme park. Many feet will be hurting, and some women might be tripping or spraining ankles. I recall on one of the videos for the opening of Disneyland ..... some women were actually ruining the pavement with high heels on a hot day. Now, if everyone got all dressed up but continued to wear sneakers, that would be fine.
