I have six children - 2 of them are boys ages 4 and 14. I agree that there should be more aimed at boys, but Disney is all about profit. So it must not make them as much money. I would absolutely love them to do a Toy Story meal. That would be awesome, and it could appeal to both boys and girls if they add Jessie.
Also, there is a pirate room at CBR, and the Pirate's League, as well as the Jedi Training. So they have some things.
I think AoA does a good job of being a place for boys too. The cars area is great! Lion King and Nemo have male main characters. The Little Mermaid is more girly, but the rooms are blue and the pictures in the room itself are not girly. They are Prince Eric and Sebestian, I believe. My DS4 loves, loves, loves, cars annd Nemo so I am thrilled about that, but I do agree that they should have done Little Mermaid as a family suite and a neutral character as the standard room.
I understand your frustration. Maybe if enough people request it, or if more people do the boy specific activities, they will add more. And they should.
