One could argue that some of these changes keep the base price of a ticket lower while the company can still make more money off people willing to pay.
- If I don't care about park hopping, I pay less than someone who wants it.
- The creation of demand-based tickets means I can choose to go on days that cost less.
- I always leave the park after the fireworks. Why should the price of my ticket subsidize to keep it longer open when I am not there?
- I buy tickets and use them, not hold them for a rainy day. Why should I subsidize the cost of the labor and effort to create a tracking system for hundreds of various ticket types to keep them non-expiring for decades?
In the end, Disney must keep its parks as full as possible while making as much money as possible as demanded by its shareholders.
There is only one MK, filled with people of all incomes, some willing to pay more for an advantage over other guests. It's all a big balancing act.
One thing is for sure, the ticketing system will see now will continue to evolve.
