I understand what you point is and find it valid to an extent.
I'm a Mom who took my DS to WDW every year and he was never a Princess loving male kid. What will like families of young boys that are not immersed into WDW like many of us are over all impression of WDW be? Will there overall conclusion be that WDW is all about Princesses and geared towards families with girls? Will subsequent visits be to Uni because there is more for families that have boys? I can see this Freeze everything backfiring on a demographic of guests over the long haul.
Princesses are pretty gender specific unlike Lion King and Toy Story.
I am going to disagree with you.
I have seen a lot of boys at princess meals and meet and greets. I guess no one told them they weren't supposed to be there.
Conversely, pre-New Fantasyland, most of the attractions at Disney World had themes that traditionally skew male. Even now, there are really very few things devoted to princess at Disney World. Let's break it down:
Rides:
The Little Mermaid
Frozen (coming soon)
Shows:
Enchanted Tales With Belle
Beauty and the Beast Live
Voyage of the Little Mermaid
Granted, there are princesses in the parades and there are princess meet and greets. But there are tons of non-princess characters in the parades and meet and greets as well.
Can girls like Toy Story? Sure. But there are very few female characters in the cast and the ones that are there are clearly in supporting roles. Boys can like Tangled or Frozen which figures much more prominent male characters than Toy Story or Lion King features female characters.
Sorry if this comes across like I'm going off on you. This isn't directed at anyone in particular. But the idea that Disney World is in any danger of becoming repellent to boys and a haven to girls is a myth.
