Who thinks about ticket prices when going to Disney? The demand of Disney is relatively inelastic. They could double their prices and lose nowhere near half their patrons.
I disagree. Check out some of the other boards you may find price does matter to many. The budget board, the disney for families board all have threads with the challenges of the current price.
Price doesn't matter to some, including my family. But it does matter to many. We have taken some families with us to Disney that wouldn't be able to go without our assistance. I know of other families that want to go but look at the price of tickets and everything else and decide Disney will never be for them.
Also, some families will go to Orlando and visit Universal, or Seaworld or Busch Gardens because access to those theme parks are much, much cheaper.
I believe Disney is aware of these, and other, limitations and will not put themselves in a position where their theme park prices are a matter of great contention.
