Cosplay? really? C'mon now...sounds like a desperate attempt to just prolong an argument that shouldn't be existant in the first place. cos-play is the representation of a ficticious character or genre
You know what I find funny about this entire scenario is that Disney has always been heavily criticized about the lack of quality and the degradation of the values that Disney once held in high standard; yet when a family or a group of people wish to add to that quality that other feel is so lacking THEY get criticized for doing so. They get called a possible distraction for wanting to maintain the integrity that Disneyland once brought out in people??? THEY ARE DRESSING UP! Hands Down! When I dress up I sport a suit and tie and, when they dress up (as Elsa and BroadSword have already stated) this is how they do it. Not just for Disneyland. If I had the vintage clothes collection I would do the same exact thing with me and my daughter.
I have always stayed true to saying that going to Disneyland is always an event in itself, up until the start of the AP it was like that for a majority of people. If they want to celebrate their trip by enjoying it dressed up and experiencing the park in a way that they feel is special to them and close to their heart then so be it. They are NOT representing ficticious people, they are NOT giving themselves fake names or acting in a "cos-play" manner. They are just enjoying the park as a family wearing what they feel brings out the best in them...
enough is enough man...these boards never cease to amaze me
