Disney builds are very much driven by their P&L entries. Sadly they seem to like to expense over years.
My only hope here is that EPIC is bringing some heat. Not only is the Classic Monster land and Harry Potter bringing excitement but they've got the kids too with Mario Kart and Super Nintendo, How to Train Your Dragon and more.
Yes.
We live in a highly litigious society. Too many parents do not supervise their children on other people's property, they get hurt and then they sue the property owners. Disney has deep pockets and is constantly dealing with lawsuits from guests who created their own problem. The best option for businesses is not have anything available to entice parents to leave their children unattended. And sadly we live in a place where there are too many people with bad intentions. I would never allow my children out of my sight in public places, only my yard. In fact we have a 6-8 ft fence all the way around our property to keep my kids and dogs in, and others out.
Disney has playgrounds at their hotels, a few place spaces in parks but parents are always expected to supervise them.
