Pioneering the Universe Within!
I am not saying you are wrong but that makes NO sense to me. Wreck it Ralph left for Big Hero Six. So why would Incredible have to leave too? Why get rid of two meet and greets for one?
The Studio was paying for Hiro and Baymax to promote the film. When they stopped paying (and the expenses would shift to the park), the park dropped the Incredibles meet and greet in order to pay for the new expense of Hiro and Baymax.
