I answered a similar thread question more seriously before, but this one I'll be a little more outlandish. I've liked a few ideas I've seen so far, but ultimately, the biggest most controversial change with be related to changing the behavior of all guests.
First off, in order to enter property you will have to have completed a basic IQ test, taken a Disney mandatory safety & manner school, and sign a contract saying you will obey all property rules and policies.
Second, park admission will be significantly lowered, but you will visit on a point based system. Each Guest will be given a perfect score of 100. Points will be deducted for not following the rules or being rude: from jumping off rides to littering, using flash on dark rides to cursing out Cast Members. Depending on the action, points will be taken off your score. At the end of the day, you must has a score of 70 or above otherwise, you pay an additional fee. If your score reaches 25, you will be asked to leave the park for the day. 4 or more visits with scores 25 or below will result in being banned from visiting for 10 years. In order to cancel that, you have to pay a premium AND take another course on how to behave properly.
If you are caught doing good, you can help bring your score back up. Guests who have a score of 150 or above at the time they leave, will get their choice of a free souvenir or a portion of their admission back.
The goal is promote the good moral values that Disney teaches in its movies and reward people for being good and punish those for being bad.
Examples of Reasons to Lose Points
-Littering
-Not Telling the Truth
-Line Jumping
-Blocking the View of Others vis child, balloon, camera, large object, etc
-Flash photography where prohibited
-Smoking where prohibited
-Blocking walkways and exits
-Not controlling children
-Climbing on things you shouldn't
-Climbing over/under chains
-Not using your manners
-Being too loud indoors
-Being on your cell phone on an attraction/show
-Parking your stroller/ECV in the wrong spot
-Cursing
-Being rude to other guests or cast members
-Trying to scam Disney or cheat the system
Examples of Things You Get Extra Points For:
-Picking Up Trash/Cleaning up messes
-Allowing smaller children to move in front of you to see better
-Random acts of kindness like paying for someone's meal
-Sitting down to watch parades and fireworks
-Holding the door open for someone with their hands full
-Recognizing a Cast Member for doing a great job
-Well mannered children
Cast Members would have a similar point based system on how they perform to strive for the best. This includes executives not only based on profits but quality of the parks as well.
All in all, if no other changes are made, the parks will be a much different but much better place for everyone. Weed out everyone that doesn't deserve to visit or work their and it leaves the best for an amazing experience. And trust me, don't worry about the money lost from restricting access to Guests, they'll pay for it if they act rude, selfish, mean, or dumb. That's where Disney will rake it in...until the world can finally live in peace & harmony at least.
Oh yeah, and Fastpass would disappear and the parks would receive the attention and creativity they deserve.
