I would love to see guests in wheelchairs aswell. [heart]
I guess toilets won't be a problem as they are designed to work right now. The toilet is just two gates in a box; one for entering at the left and one for exit at the right. You can't se any division of gender and it's highly imaginable this happens inside the facility. As well for disabled toilets I imagine. So they won't need to design an extra toilet just for implementing disabled people. I'm more concern about the animation for getting them in and out of the different rides.
