I'm not sure less informed guests are the company's fault.
The people who arrive with no idea where they are or what there is to do are just.. well.. idiots. Along those lines, providing park maps/collateral media and good signage is a key to avoiding these situations.
An example of "expecting too much of a guest" is when they eliminate all the smoking areas except for two at the MK and don't make this information available anywhere but on the maps they've discouraged guests from getting and the app (hidden deep within it). The obvious solution is a simple sign that says "No smoking here, nearest location is XYZ" at the old locations.
But adding a third park and having it cost a different amount will clue most people in - plus the attractions are all slides. I dont think it will be an issue if they deliver on the show elements.
